Dutasteride Before and After: 10 Success Stories

Article Summary

Oral dutasteride is one of the most powerful treatments for androgenic alopecia, offering deeper DHT suppression than finasteride. But what kind of results should you realistically expect? In this article, we break down how dutasteride works, what clinical studies actually show, how typical outcomes will vary from online anecdotes, and why your personal results depend on more than just the drug itself. We also explore timelines, survivorship bias, and how combining therapies can boost outcomes and narrow the curve of unpredictability. If you’re considering oral dutasteride, this guide will help you set grounded expectations and make informed treatment decisions.

When it comes to hair loss treatments, oral dutasteride often emerges as the most powerful option, consistently outperforming FDA-approved alternatives like finasteride in clinical studies. Across the internet, personal stories echo this sentiment: discussion boards and Reddit threads feature dramatic recoveries, with some users claiming transformations from advanced thinning to a full, healthy head of hair.

(You can read more about this one below.)

However, online spaces tend to spotlight the extremes, either remarkable success stories or reports of failure, creating a distorted picture of what typical results look like. 

So, where does dutasteride truly stand? How do we distinguish between what’s possible and what’s probable? How can you weigh anecdotal experiences against the outcomes you’re most likely to see? And importantly, what might your pattern of regrowth look like after 1, 2, 3, or even 10 years of therapy?

This article addresses these questions directly. We’ll set clear expectations for oral dutasteride, explore how to interpret results shared online, highlight some of the most dramatic dutasteride before and after photos, and offer guidance on what an average treatment journey may look like. 

Finally, we’ll introduce a framework you can use to evaluate and compare all hair loss therapies, helping you see dutasteride ranks in terms of regrowth potential, evidence quality, and long-term safety.

Quick Refresher on Androgenic Alopecia (AGA)

Androgenic alopecia (AGA) is the most common form of hair loss affecting both men and women, marked by progressive thinning and miniaturization of hair follicles. This is primarily thought to be a result of genetic predisposition and the influence of androgens, especially dihydrotestosterone (DHT).^[1]Chen, S., Xie, X., Zhang, G., Zhang, Y. (2022). Comorbidities in Androgenetic Alopecia: A Comprehensive Review. Dermatology and Therapy. 12(10). 2233-2247. Available at: … Continue reading 

There is a huge choice of treatment options for AGA, with FDA-approved therapies such as topical minoxidil and oral finasteride. Many other options are either used off-label or under investigation, including low-level laser therapy, platelet-rich plasma injections, hair transplant surgery, herbal compounds, and emerging agents like prostaglandin analogs and caffeine-based solutions.^[2]Bajoria, P.S., Dave, P.A., Rohit, R.K., Tibrewal, C., Modi, N.S., Gandhi, S.K., Patel, P. (2023). Comparing Current Therapeutic Modalities of Androgenic Alopecia: A Literature Review of Clinical … Continue reading This diversity reflects both the complexity of the disease and a significant unmet need in achieving consistent, satisfactory results for patients.

Despite existing for decades, oral dutasteride has recently surged in popularity as an off-label AGA treatment. Like finasteride, it inhibits the conversion of testosterone to DHT. But it blocks both type I and II 5-alpha-reductase enzymes more effectively, potentially offering a more potent effect. 

Dutasteride 101

Dutasteride blocks both type I and type II isoforms of the 5ɑ-reductase enzyme. This enzyme converts testosterone to DHT, a key hormone driving male pattern hair loss and prostate growth. By inhibiting both isoforms, dutasteride causes a near-complete suppression of DHT, reducing its levels in blood by up to 98%, which is higher than finasteride’s reduction of around 65-70%.^[3]Clark, R.V., Hermann, D.J., Cunningham, G.R., Wilson, T.H., Morrill, B.B., Hobbs, S.

Comparison of Clinical Trials with Finasteride and Dutasteride. Reviews in Urology. 6(Suppl 9). S31-S39. Available at: PMID: 16985923

The standard and most studied dose is 0.5 mg daily. This is the FDA-approved dose for benign prostatic hyperplasia and the most common dose used off-label for hair loss. Lower doses like 0.2 mg daily have been used in one clinical trial, though 0.5 mg remains the norm.^[5]Escamilla-Cruz, M., Magana, M., Escandon-Perez, Bello-Chavolla, O.Y. (2023).

Why “Expectation Setting” Matters

Realistic expectation setting is fundamentally important for anyone starting their AGA treatment journey, particularly with treatments that do not have a large amount of evidence.

Some people may expect dramatic hair regrowth, often influenced by online testimonials or dutasteride before and after photos showing “hyper responders”.

Others may experience disappointment, frustration, and a decline in self-esteem when their own results are modest or average.

On the other hand, those with overly low expectations may forgo potentially beneficial treatments altogether, missing out on improvements that could positively impact their quality of life.

Online before-and after photos and personal anecdotes present another challenge. They are not standardized, can be misleading, and often feature individuals who have responded exceptionally well to a product, rather than the majority who see more moderate effects. These images rarely account for factors like lighting, hair styling, photo angles, or even digital enhancement, all of which can distort perceived efficacy.

To help guide your treatment selections & expectations, here are two key principles that, once understood, will make all the difference in how you approach your hair growth journey.

Principle #1: What’s Possible ≠ What’s Probable

Consider the following chart.

Note the individual datapoints and how scattered they appear. Also note the trendline, which represents the average of all individual datapoints shown in the chart.

The individual datapoints represent what’s possible for any one individual. The trendline represents what’s probable.

 

Resultantly, people see these dutasteride before and after success stories, and think, “This is all I see. And so I’ll probably get the same regrowth, too.” This shifts their expectations for the drug far above the trendline:

Then they try dutasteride and either quit too early to see regrowth (more on that soon)… or they don’t get the same results, and determine (often erroneously) that the drug just isn’t working for them.

The solution: don’t set expectations by what’s possible. Set expectations by what’s probable. Understand the trendlines for oral dutasteride: when results will typically first start to show, when results will peak and/or plateau, and what results will look like 5+ years into the future.

You can do this by using a standardized rubric we created called Regrowth Potential.

Regrowth Potential

As mentioned above, Principle 1 shows us that results tend to scatter across a spectrum: some datapoints high, some low, with a trendline running through the middle. The problem is that online anecdotes usually highlight only the high datapoints, while clinical trial data can feel abstract and hard to translate into lived experience. 

Regrowth Potential is our way of standardizing this landscape. It’s designed to cut through anecdotal extremes and align patients with the trendline, what most people can realistically expect.

So what does the average look like?

Most people see stabilization first, regrowth second, and a slowing of hair loss, with partial reversal layered on top. 

Gains usually peak within 6-12 months, then plateau.^[8]Nestor, S, M., Ablon, G., Gade, A., Han, H., Fischer, D.L. (2021). Treatment options for androgenetic alopecia: Efficacy, side effects, compliance, financial considerations, and ethics. Journal of … Continue reading

Typical regrowth brings hair back to where it was 1-3 years earlier, not to pre-hair-loss density. 

And what influences where you fall on that spectrum?

1. How long you’ve been losing hair: Earlier intervention = higher trendline. Long-standing bald spots rarely respond.^[9]Feldman, P.R., Gentile, P., Piwko, C., Motswaledi, H.M., Gorun, S., Pesachov, J., Markel, M., Silver, M., Brenkel, M., Feldman, O.J., Kamen, C.L., Uleryk, E., Guevara-Aguirre, J., Fiebig, K.M. … Continue reading 
2. Which therapy you use: Some are more effective at certain stages or patterns.
3. How consistent you are: Skipped doses or stopping early push results below the trendline.

Most patients should expect stabilization and modest regrowth. A small minority will experience “hyper-responsiveness,” but these rare outcomes should not set the benchmark. 

Principle #2: Poorly-Studied Treatments = More Variability In Results

When fewer studies exist on a treatment, expectations for hair regrowth become harder to pin down. With limited data, some patients may get spectacular results, while others see very little. But, without enough trials, it’s nearly impossible to know how common each outcome really is.

Take finasteride and oral dutasteride as examples. Finasteride has been tested in dozens of randomized controlled trials, which means we can say with high confidence what the average regrowth looks like and where most patients will land. Oral dutasteride, by contrast, has fewer high-quality studies. 

That doesn’t mean dutasteride is ineffective. In fact, the regrowth gains by dutasteride have often outperformed finasteride users. But it does mean the range of possible outcomes is wider, with more unpredictability between “great responders” and “minimal responders”. 

When it comes to understanding expectations for androgenic alopecia treatments, the normal distribution model helps clarify why individual results can be so different, even when clinical averages sound reassuring. Treatment outcomes typically form a bell-shaped curve rather than a single value, meaning people experience a range of responses. 

• Clinical averages, which are often cited in studies, represent the peak of this curve, not the experience of every patient. Most individuals see results somewhere near this average, but plenty fall above or below it.

• Wide curve (high variability, low evidence): When evidence for a treatment is limited or inconsistent, like with newer therapies, the curve is broad. Some may see fantastic regrowth, others very little, and outcomes are harder to predict. 
• Narrow curve (predictable outcomes, high evidence): For well-researched medications, the curve is tight. Most people’s results cluster close to the average, giving new patients more confidence in knowing what to expect.

Importantly, average never means “everyone”. Treatment outcomes often show a spread, so while clinical trials help set realistic expectations, individual journeys may differ depending on genetics, age, stage of hair loss, and treatment adherence. 

This variability also explains why anecdotes online can feel so misleading. When people share their results in forums, they’re often the outliers, the best or worst cases. On a scatterplot of individual datapoints, these stories sit at the edges. With dutasteride, the scatter is typically above the trendline, meaning a Reddit “success story” may be far removed from what most users should expect.

The rubric we can use to get a sense of whether our results will be predictable or variable is Evidence Quality.

Evidence Quality

Evidence quality answers the question “How reliable is the evidence that this intervention will actually help regrow my hair?” The strength of this evidence is determined not only by the number of studies available but also by their design, especially RCTs, which typically provide the most trustworthy evidence.

The concept of confidence in treatment outcomes can be likened to a game show in which money is hidden behind two doors. Behind door number 1, the amount of money behind it could be anywhere between $0 and $100. You might walk away with nothing, a little, or a lot, and there’s no way to know for sure, because there just isn’t enough evidence to narrow down the possibilities. 

With door number 2, the money behind it ranges tightly between $49 and $51. Because so many high-quality studies exist, you can be confident that your outcome will almost certainly fall within this narrow window, making it much easier to know what to expect.

More evidence means a smaller range and greater predictability; less evidence means more uncertainty and a wider range of possible outcomes.

Relating this back to oral dutasteride, the treatment has fewer published randomized controlled trials compared to finasteride. This means less outcome certainty, so patients considering dutasteride face a wider bell curve of potential results (as shown above), from exceptional regrowth to only minor improvement.

To summarize: 

• More and better studies = tighter confidence around the true average results
• Fewer studies = more uncertainty, a wider range of possible outcomes, and less ability to predict what will happen for any individual. 

Understanding the evidence quality of a treatment empowers patients to interpret clinical claims and anecdotal stories with a critical eye, helping them choose interventions with the best established track record and manage expectations where data is still emerging.  

Anecdotal Successes

In the world of hair loss drugs, Redditors and hair loss forums tend to overshare the best of what’s “possible”. 

Let’s have a look at 10 real-life anecdotal reports shared by Reddit users. 

It goes without saying that the experiences related below, including any before-and-after photos, are anonymously submitted by users and strictly represent their personal experiences. They are not considered medical evidence, nor should they be relied upon as medical advice. 

It should also be noted that some of these individuals used other treatments alongside dutasteride to assist in their hair regrowth journey. With combination treatments, it is not easy to see what’s causing the hair growth, so we need to be even more cautious about the success seen.

Case 1: 14-month course of oral dutasteride 0.5 mg daily

This 25-year-old male reported aggressive hair thinning between ages 19–21, which he reportedly stabilized with dutasteride monotherapy at 0.5mg/day. He had previously tried finasteride for about a year but did not report any visible regrowth. The patient described significant regrowth of previously thin hairs, with increased hair density compared to treatment start. He noted that there were no side effects throughout treatment. Notably, he mentioned that finasteride provided stabilization only, while dutasteride produced visible regrowth after one year of use. Other users also highlighted the greater potency and longer half-life of dutasteride compared to finasteride.

Case 2: 10-month course on dutasteride 0.5 mg and oral minoxidil 0.625 mg daily

A female individual (age unspecified) with diffuse thinning, especially around the parting, reported on her experience using dutasteride 0.5mg/day, along with oral minoxidil 0.625mg/day (which was scaled back from an initial dose of 1.25mg). Further into the treatment, she added topical minoxidil to her treatment stack. At the 10-month mark, she reported a significant increase in hair density compared to baseline, with notable thickening at the part line, as confirmed by the user-submitted photos. The user was delighted with her results and intends to decrease her dutasteride use to a maintenance dose eventually. 

Case 3: 10-month course on dutasteride 0.5 mg and oral minoxidil 5 mg daily

This report was from a 26-year-old male with clearly noticeable balding by age 20 and a family history of male pattern baldness, including his father and both grandfathers. The user’s protocol included oral dutasteride 0.5mg and oral minoxidil 5mg daily. The user noted heavy shedding in the first two months of treatment, with the first noticeable signs of improvement appearing at months 2-3, before achieving a successful outcome by month 10, when they reported marked hair thickening and a renewed sense of confidence and self-esteem. The user did not report any side effects from dutasteride, but linked minoxidil use to a mild increase in arm hair. It’s worth noting that the user’s physician had recommended he switch from his initial finasteride therapy to dutasteride due to their “aggressive” alopecia.

Case 4: 3.5 months on oral dutasteride 0.5 mg and minoxidil 5 mg daily

A 22-year-old male shared his experience using oral dutasteride (0.5mg/daily), oral minoxidil (5mg/daily), plus dermarolling (1.5mm/weekly) for 3.5 months. The user achieved significant increases in hair density and regrowth, a self-reported improvement in self-esteem, and no reported side effects, namely as to his libido and sexual function. He noted his consistent use and starting relatively early in the hair loss process as reasons for his favorable outcome. Additionally, he highlighted that he did not titrate up to his final doses but started the full protocol from day one.

Case 5: 6 months on dutasteride 0.5 mg (ed 1st month – 3x/wk) + microneedling 1.0 mm weekly

This male (23 y/o) used dutasteride at the dose of 0.5mg daily for the first month, then reduced to 0.5mg thrice weekly, along with microneedling 1.0mm once weekly, over the course of six months. The apparent results include hairline and temple regrowth, with the hair improving in thickness and health overall. The user did not report any side effects beyond bleeding associated with microneedling, noting that he began to notice changes within a month. In explaining his results, he also believed himself to be highly responsive to the treatment. 

Case 6: 2+ years on dutasteride 0.5 mg daily and sublingual minoxidil 0.9 mg – 2.7 mg daily

In this report, a 31-year-old male shared his results on a protocol of oral dutasteride (0.5mg daily) and sublingual minoxidil (gradually increased from 0.9mg to 2.7mg daily). While he started treatment with oral finasteride, he switched to dutasteride and sublingual minoxidil at the advice of his dermatologist. The users reported significant improvement after 3–4 months, with darker hair color and thickening of hair at the crown and mid-scalp. He added that most improvements came within 12 months, noting that he did experience any shedding with minimal side effects.

Case 7: 2 months on dutasteride 0.5 mg daily and oral minoxidil 2.5 mg daily

A 31-year-old male detailed his experience taking dutasteride 0.5mg daily alongside oral minoxidil following a series of unsuccessful treatments. He initially began with finasteride 1mg, which slowed hair loss but did not affect major regrowth. He then tried minoxidil and microneedling, before restarting finasteride and topical minoxidil alongside dermarolling. Upon switching to dutasteride, he noted major improvement in just two months, including achieving thicker hair and the disappearance of bald spots. The user reported no major side effects and noted supplementing his protocol with a daily multivitamin (Becadexamin) and a collagen supplement to support skin and hair.

Case 8: 3.5 months on dutasteride 0.5 mg daily and topical minoxidil 2x daily

A 24-year-old male reported significant improvement in hair density and coverage following 3.5 months of oral dutasteride 0.5mg/day and topical minoxidil (Rogaine) applied twice daily. The Redditor reported hair shedding, especially around the hairline, at month one. In the second half of the treatment period (months 2-3.5), however, he experienced accelerated hair regrowth with the appearance of a full head of hair. He was prescribed dutasteride directly (no prior finasteride use) and reported no major side effects as of the 3.5-month mark. 

Case 9: 1 year on dutasteride 0.5 mg daily and 10 years on topical minoxidil

This user (age 31) used daily dutasteride (Avodart 0.5mg) for one year in addition to ten years of consistent topical minoxidil use. He had previously used finasteride for two years with satisfactory results, stating that he could have achieved more regrowth by combining minoxidil with a DHT blocker. Following his switch from finasteride to dutasteride, he noted improvements in hair strength, libido increase, and clearer thinking. Months 3-8 were marked by shedding and brittle, weaker hair, with the patient considering switching back to finasteride. But after month 8, he saw thicker strands and mild regrowth. He also noted longer hair cycles, which now allow him to better maintain hair length. The user planned to continue with treatment and reevaluate at the two-year mark.

Case 10: 8 months on dutasteride 0.5 mg and 10 months on oral minoxidil 2.5 mg

This male user (29 y/o) undertook a protocol of oral dutasteride 0.5mg/day and oral minoxidil 0.5mg/day concurrently for eight months, with strong improvements in hair regrowth and thickness. He reported shedding at months 1-3 followed by regrowth starting at the 3-month mark. He observed increased hair density in the crown and temples from months 3 to 8, and noted major progress by month 10, with the crown nearly full, despite a persistent “M-shaped” hairline. The user reported no major side effects and plans to undergo a hair transplant, notwithstanding the favorable outcome. 

But these anecdotes are often far above the trendline, over “average” expectations.

Probable Regrowth Timeline for Oral Dutasteride

We have laid out a likely timeline for oral dutasteride treatment. However, this is based on four studies that we could find using oral dutasteride for hair loss, including one where it was used for frontal fibrosing alopecia.^[10]Tsunemi, Y., Irisawa, R., Yoshiie, H., Brotherton, B., Ito, H., Tsuboi, R., Kawashima, M., Manyak, M.

Month 0-3: No visible changes:

• Most studies note minimal to no observable regrowth in the first 3 months as dutasteride begins to reduce DHT levels, but hair follicles have not yet responded morphologically. 

Month 3-6: Early results seen:

• Clinical improvements in hair thickness and reduced shedding are often first noted from around month 3 onward.
• Quantitative hair count changes become statistically significant compared with placebo after 12 weeks; global photographic assessments begin to reflect mild positive change (~22-31% of subjects with slight/moderate increase at week 12).

Month 6-9: First cosmetic improvements:

• By 6-9 months, most patients exhibit visible improvement in hair density and coverage, with the peak initial response typically building upon earlier thickening. 
  • In a Japanese study, mean hair count increased significantly at 26 weeks and continued to improve at 52 weeks (68-87 hairs in a 2.54cm area).
  • Panel assessments at month 6 indicated ~75-85% of patients had some improvement in global photographs.

Months 9-15: Peak response period:

• Maximum regrowth and cosmetic benefits are typically observed within the first 12-15 months, based on clinical results.
  • “Marked improvement” rates ranged from 23-25% at 12 months with daily dosing in large cohorts. Median improvement in photographic rating scores and increases in terminal hair count continue through this period.
  • Sustained effects shown to persist up to 1 year in an open-label extension study.

Months 15-24: Maintenance phase: 

• Most patients maintain results with continued therapy, improvements plateau or slightly decline, but remain superior to baseline and other treatments.
  • Longer-term users (mean follow-up up to 17 months) show stabilization and ongoing maintenance with only rare further large gains.
  • Clinical improvement was seen in studies where doses ranged 3-7 capsules/week, with higher doses correlating to better maintenance and slightly higher efficacy.

Months 24-26: Possible plateau, limited data:

• Efficacy plateaus; possible mild regression or fluctuation, but proper adherence maintains gains for most patients. 
  • Real-world data of up to at least 24 months confirm sustainability in appropriately selected patients, especially at higher doses.
  • No long-term studies exceed 36 months, so late-stage trends remain speculative.

But what about all the success stories we see online, users on Reddit or other forums who have experienced dramatic hair regrowth?

Well, this difference usually stems from a phenomenon called survivorship bias. 

What is Survivorship Bias?

• Survivorship bias happens when the accounts you see are not representative of all experiences but are disproportionately skewed toward the most remarkable, positive cases.^[14]Rao, T. (2024). Understanding Survivorship Bias: Implications for Research and Decision-Making. Journal of Emerging Technologies and Innovative Research, 11(6). JETIR2406276
• People with extreme positive results are much more likely to post about their experiences, eager to share their success.
• In contrast, those who experience average or mediocre outcomes (which is the majority) rarely feel motivated to post.
• As a result, the outcomes you typically see online are samples from the tails of the bell curve: exceptional or very poor cases, not the “center” or average results.

Clinical Trial vs. Online Reports

• Clinical trials measure average results across a large, diverse population, using objective metrics.
• Online reports are anecdotal and self-selected. Because impressive transformations are inspiring, these are far more likely to be posted and shared.
• This dynamic can mislead readers into believing that dramatic regrowth is almost guaranteed, when in reality it is just one possibility among many, and not the most probable outcome.

Combining Treatments: Narrowing the Curve

While oral dutasteride is one of the most effective monotherapies for AGA, if you want to increase your odds of good results, combining it with additional therapies can have a dramatic impact. 

Studies have shown that adding minoxidil to dutasteride can further improve regrowth outcomes, leveraging the vasodilatory and follicle-activating effects of minoxidil, alongside DHT suppression from dutasteride.^[15]Obeid, M.N.A., Fattah, N.S. A., Elfangary, M.M., Al Husseni, R.M. (2024). Comparison between topical minoxidil 5% alone versus combined with dutasteride (topical 0.02% through microneedling or oral … Continue reading

Furthermore, adding low-dose dutasteride to ongoing finasteride therapy in patients with suboptimal response resulted in a dramatic increase in hair density, suggesting that combined therapy can be beneficial for those not fully responding to finasteride alone.^[16]Boyapati, A., Sinclair, R. (2013). Combination therapy with finasteride and low-dose dutasteride in the treatment of androgenetic alopecia. Australasian Journal of Dermatology. 54(1). 49-51. … Continue reading 

Going back to the bell curves, more modalities = less variability. By targeting different mechanisms (like minoxidil) or by targeting more types of 5-alpha-reductase (like in the finasteride study), outcomes become less dependent on any single pathway. This leads to more predictable, less variable results across a wider patient group.^[17]Mysore, V., Kumaresan, M., Dashore, S., Venkatram, A. (2023). Combination and rotational therapy in androgenetic alopecia. Journal of Cutaneous and Aesthetic Surgery. 16(2). 71-80. Available at: … Continue reading 

How Can I Maintain “Realistic Expectations”?

To keep realistic expectations on oral dutasteride for hair regrowth, it’s critical to understand both the typical timelines and the nature of outcome variability:

What does “realistic” mean?

• Realistic does not mean pessimistic: Most users will benefit, but responses vary between individuals. A realistic expectation is based on clinical averages, not the best or worst case.
• Don’t expect to be “cured” of your hair regrowth. Most treatments “rewind the clock” a certain amount. Oral dutasteride may reverse hair loss by 6-24 months on average. However, dramatic multi-year regrowth is much less common, possible but not probable for most users.
• Your most probable result is noticeable improvement and stabilization, rather than full reversal of all past hair loss. 

Practical Takeaways

• Be patient: Oral dutasteride takes time – most users don’t see meaningful change until at least 6 months in, with optimal results often peaking around 12-15 months. 

• Track your own progress: Use consistent photos or, ideally, hair counts in a fixed area to monitor changes. Comparing to internet success stories often skews expectations and reflects outliers rather than the norm.

• Define success on your own terms: For some, success means stopping hair loss. For others, it’s regaining density. Know what you’re aiming for and adjust expectations accordingly. 

• Consider combination treatments: Pairing dutasteride with therapies like minoxidil or microneedling may improve outcomes and reduce variability, especially if you’re not seeing early improvements. 

• Use clinical data to ground your expectations: Clinical trials give you an average expectation, not a guarantee. Use online anecdotes as inspiration, not prediction.

Final Thoughts

Your expectations for any hair loss treatment, even oral dutasteride, should rest on two key pillars:  regrowth potential x evidence quality.

Together, they shape your position on the “bell curve” of likely outcomes.

• If you’re early in your hair loss journey, consistently take the medication, and possibly combine it with other therapies, you’re more likely to end up closer to the favorable side of the curve.
• If your hair loss is advanced or you’ve tried many options before, you might fall closer to the average or lower end.

Either way, understanding that most people land somewhere near the middle of the curve, not at the extremes, helps you avoid frustration and stay committed.

Setting expectations isn’t about limiting hope or being overly pessimistic; it’s about anchoring your treatment outcomes to reality, so you can make better, more sustainable decisions about your treatment journey.
