Minoxidil Before and After Photos [2025] | Does It Work?

Article Summary

Topical minoxidil is the most widely used hair loss treatment, with decades of clinical evidence supporting its effectiveness. But while many experience stabilization and regrowth, others see little to no change. Learn why minoxidil response is so variable, how to interpret before-and-after photos, and what strategies can help improve results.

Full Article

Topical minoxidil has been a cornerstone of androgenic alopecia (AGA) treatment since its FDA approval in the 1980s. With millions of users worldwide, it stands as one of the most widely adopted therapies for hair loss, supported by decades of clinical evidence, and an enormous body of real-world anecdotes, reviews, and before-and-after photos. 

However, results with minoxidil can be highly variable, and this variability can be traced in part to biological differences, particularly in the activity of the sulfotransferase enzyme (SULT1A1), which is responsible for converting minoxidil into its active form. Not everyone sulfates minoxidil effectively, meaning that while some achieve meaningful regrowth, others see little to no improvement.

Adding to this challenge is the influence of online topical minoxidil before and after photos (like you can see below), which can create inflated expectations compared to the more modest, probable outcomes seen in practice. 

This article will break through that noise to answer a critical question: when it comes to minoxidil, what is actually the most probable result, not just possible? 

First, let’s take a look at what topical minoxidil is.

Refresher: What is Topical Minoxidil?

Topical minoxidil was the first therapy ever approved by the FDA for the treatment of AGA, making it a landmark in the medical management of pattern hair loss.^[1]Suchonwanit, P., Thammarucha, S., Leerunyakul, K. (2019). Minoxidil and its use in hair disorders: a review. Drug Design, Development and Therapy. 13. 2777-2786 Introduced in the 1980s, it has since become one of the most widely available and researched treatments across the globe. Its primary action is as a potassium channel opener, which helps to stimulate blood flow, prolong the hair’s growth phase (anagen), and increase follicle size, mechanisms that together can support thicker, denser hair regrowth over time.^[2]Messenger, A.G., Rundegren, J. (2004). Minoxidil: mechanisms of action on hair growth. British Journal of Dermatology. 150(2). 186-194. Available at: https://doi.org/10.1111/j.1365-2133.2004.05785.x

Minoxidil is known as a “pro-drug”, meaning that it needs to be activated within the body to exert its effect. The enzyme responsible for this is called sulfotransferase or, more specifically, SULT1A1. The level of sulfotransferase activity differs depending on the individual, which means that the effectiveness of treatment also differs depending on who you are.^[3]Pietrauszka, K., Bergler-Czop, B. (2020). Sulfotransferase SULT1A1 activity in hair follicle, a prognostic marker of response to the minoxidil treatment in patients with androgenetic alopecia: a … Continue reading 

Formulations typically come in 2% and 5% strengths. The 2% solution was originally FDA-approved for women, while the 5% concentration was approved for men; however, both are now commonly used off-label across genders. Beyond these standard strengths, compounding pharmacies have made higher concentrations available for patients seeking more individualized treatment approaches, with some online telehealth providers (such as Ulo) offering customized formulations. Standard dose topical minoxidil is available over-the-counter in most countries, ensuring accessibility without the need for a prescription.

The Evidence

Topical minoxidil’s robust efficacy for hair regrowth is supported by dozens of high-quality randomized controlled trials (RCTs) and meta-analyses across men and women, consistently demonstrating average increases in hair count of around 10-20% over 6-12 months. 

We have collated many of these studies into a table, which you can look at here. However, we have summarised some of the most recent topical minoxidil studies.

Liang et al. (2022)

• Prospective, evaluator-blinded RCT with 120 women with female pattern hair loss (FPHL) assigned to three groups: 5% topical minoxidil alone; 5% minoxidil + oral spironolactone (80-100 mg); and 5% minoxidil and microneedling every 2 weeks.^[4]Liang, X., Chang, Y., Wu, H., Liu, Y., Zhao, J., Wang, L., Zhuo, F. (2022). Efficacy and Safety of 5% Minoxidil Alone, Minoxidil Plus Oral Spironolactone, and Minoxidil Plus Microneedling on Female … Continue reading
• Duration: 24 weeks; outcomes measured included dermascope, ultrasound biomicroscopy, physician, and patient assessments.
• Effective rate at week 2:
  • 55.27% (topical minoxidil)
  • 86.49% (topical minoxidil and oral spironolactone)
  • 95% (topical minoxidil and microneedling)
• Combo therapies (Groups 2&3) outperformed topical minoxidil alone for hair density, shaft diameter, scalp/thickness, shedding, and quality of life; Group 3 showed the greatest benefit.
• Adverse effects were reported across all groups; more menstrual disorders were reported in the spironolactone group. Main limitations: small sample, exclusion of severe cases, possible bias from unblinded treatments.

Hassan et al. (2022)

• Comparative study in 60 women with FPHL: 5% minoxidil topical foam and oral vitamin D3, minoxidil foam only, or vitamin D3 for 12 weeks (plus 15 controls for vitamin D comparison).^[5]Hassan, G.F.R., Sadoma, M.E.T., Elbatsh, M.M., Ibrahim, Z.A. (2022). Treatment with oral vitamin D alone, topical minoxidil, or combination of both in patients with female pattern hair loss: A … Continue reading 
• Primary outcomes: reduction in thin hair count and Ludwig stage improvement via clinical and dermoscopic evaluation. 
• Best results from combination therapy (minoxidil foam and vitamin D3), followed by minoxidil foam alone; vitamin D3 monotherapy had minimal effect.
• Vitamin D3 appeared to enhance minoxidil efficacy, though the sample size was small, and adverse events were not reported. 

Bao et al. (2022)

• RCT with 71 men, split into: 5% topical minoxidil twice daily, electrodynamic microneedling every 3 weeks, or topical minoxidil and microneedling combined.^[6]Bao, L., Zong, H., Fang, S., Zheng, L., Li, Y. (2019). Randomized trial of electrodynamic microneedling combined with 5% minoxidil topical solution for treating androgenetic alopecia in Chinese males … Continue reading
• Follow-up: 24 weeks, with an additional 6-month observation period.
• All treatments increased non-vellus hair density; the combined group had the greatest improvements in hair density and diameter. 
• The combination group received additional scalp massages (potential confounder); 12 participants experienced adverse reactions (dermatitis, dandruff, lymph node enlargement), none severe.

Singh et al. (2020)

• Double-blind, placebo-controlled RCT in 80 men: Groups received either 5% topical minoxidil, 5% topical minoxidil and PRP injections, placebo, or PRP alone.^[7]Singh, S.K., Kumar, V., Rai, T. (2020). Comparison of efficacy of platelet-rich plasma therapy with or without topical 5% minoxidil in male-type baldness: A randomized, double-blind placebo control … Continue reading
• 12 weeks’ treatment with 2-month follow-up; outcome: changes in total, terminal, vellus, and non-vellus hair density, pigmentation, and global assessments.
• Highest hair density and satisfaction with topical minoxidil and PRP; both monotherapies are better than placebo, but the combo was most effective.
• Limitations: short-term follow-up, some subjective outcomes; low adverse event rate (mostly mild, e.g., scalp pruritus, facial hair growth).

Overall, when you look across all of the data, consistent benefits are seen with topical minoxidil usage. However, these results are variable. The key reason for this is differences in sulfotransferase activity. As we mentioned before, minoxidil is a pro-drug, and it needs to be enzymatically activated to exert its effect. We will go into more detail about this below.

What’s Possible ≠ What’s Probable

When evaluating treatment outcomes, especially online minoxidil before and after photos, it’s important to separate possibility from probability. The scattered data points below show the full range of what might occur for individuals, while the central trendline reflects the average outcome (i.e., what typically happens).

Online anecdotes often showcase what we would call “hyper-responders” – people who experience dramatic results. These people may also have higher levels of sulfotransferase activity.

These stories, while real, represent outcomes that are well above average. The issue arises when patients focus only on these peak results and expect the same for themselves. If their own progress seems slower or less dramatic, they may stop prematurely or mistakenly believe the treatment is ineffective.

Dramatic results are often showcased more than modest outcomes because of survivorship bias. This bias occurs when only the most striking successes are noticed or shared, while the many average or less impressive results go unreported.

Why Results Are Variable: The SULT1A1 Enzyme

Minoxidil must be converted into minoxidil sulfate by the sulfotransferase enzyme SULT1A1, which is present in the outer root sheath of hair follicles, to become pharmacologically active and stimulate hair growth. 

Several peer-reviewed studies confirm that the level of SULT1A1 activity in scalp follicles is a key determinant of how well a patient responds to minoxidil therapy.^[9]Goren, A., Castano, J.A., McCoy, J., Bermudez, F., Lotti, T. (2014). Novem enzymatic assay predicts minoxidil response in the treatment of androgenetic alopecia. Dermatologic Therapy. 27(3). 171-173. … Continue reading Enhancing SULT1A1 activity, such as by using enzyme-boosting adjuvants, has been shown in recent trials to convert a majority of prior non-responders into responders, further confirming the mechanistic role of this enzyme.^[10]Chandrashekar, B.S., Chandu, M., Shenoy, C., Chander, A., Roopa, M.S. (2024). SULT1A1 enzyme booster to amplify topical minoxidil response in androgenic alopecia: a single-center prospective study. … Continue reading 

This enzyme-based variability explains why two people can apply minoxidil in the same way but see very different outcomes, and why more than half of users may see only limited or no benefit despite consistent application.

Fixing the Enzymatic Problem

A number of evidence-based strategies exist to improve minoxidil response. These include microneeding, retinoic acid co-application, formulation changes, consistency, and combination therapy.

Microneedling

Multiple systematic reviews and clinical trials confirm microneedling significantly improves minoxidil efficacy. A 2023 meta-analysis showed that combining the two led to a significantly greater increase in hair count compared to minoxidil alone, regardless of needle depth or device used. Hair count improvements are notable after 12 to 24 weeks of combined treatment.^[11]Ahmed, K.M.A., Kozaa, Y.A., Abuawwad, M.T., Al-Najdawi, A.I., Mahmoud, Y.W., Ahmed, A.M., Taha, M.J.J., Fadhli, T., Giannopoulou, A. (2025). Evaluating the efficacy and safety of combined … Continue reading

Retinoic Acid (Tretinoin)

Topical tretinoin has been shown in peer-reviewed studies to upregulate follicular SULT1A1, thereby enhancing the conversion of minoxidil to its active form. In a 2019 study, tretinoin not only improved clinical response in difficult cases but also increased scalp SULT1A1 activity, supporting its role as a mechanistic booster.^[12]Sharma, A., Goren, A., Dhurat, R., Agrawal, S., Sinclair, R., Trueb, R.M., Vano-Galvan, S., Chen, G., Tan, Y., Kovacevic, M. (2019). Tretinoin enhances minoxidil response in androgenetic alopecia … Continue reading

Formulation Adjustments (Foam vs. Solution 2% vs. 5%)

Clinical research shows that 5% minoxidil is more effective than 2% for both men and women. Foam is as effective as a solution but better tolerated, with reduced risk of contact dermatitis due to the absence of propylene glycol. Some evidence suggests liquid formulations might yield slightly higher absorption, but both forms are clinically comparable.^[13]Purnak, T., Senel, E., Sahin, C. (2011). Liquid formulation of minoxidil versus its foam formulation. Indian Journal of Dermatology. 56(4). 462. Available at: https://doi.org/10.4103/0019-5154.84714 

Consistency and Adherence

Missed doses can reduce topical minoxidil efficacy. Some clinical guidance suggests that missing minoxidil applications even once per week can diminish results, and consistent, daily use is necessary to achieve and maintain hair regrowth.^[14]Shadi, Z. (2023). Compliance to Topical Minoxidil and Reasons for Discontinuation among Patients with Androgenetic Alopecia. Dermatology and Therapy. 13(5). 1157-1169. Available at: … Continue reading 

Combination Therapy

Combining minoxidil with finasteride/dutasteride, PRP, low-level laser therapy (LLLT), or, in resistant cases, oral minoxidil, provides superior results versus monotherapy. Meta-analyses and randomized trials consistently find greater improvement in hair density, count, and patient satisfaction when using combination regimens.^[15]Xia, Y., Chen, H., Chen, Y., Chen, Z. (2025). Relative efficacy of minoxidil in combination with other treatments for androgenic alopecia: a network meta-analysis based on randomized controlled … Continue reading 

So, what do online topical minoxidil before and after photos look like?

Online Topical Minoxidil Successes

Now that we have discussed how topical minoxidil works, potential regimens, and likely timelines, here are 10 reports published by Reddit users with before and after photos.

Disclaimer: The stories below are unverified anecdotes. Consequently, they illustrate individual outcomes and should not be construed as clinical proof or medical advice.

Case 1: Male (age unknown), 6 months on topical minoxidil monotherapy (5% once daily)

This individual applied 5% topical minoxidil once daily for six months. They chose topical minoxidil out of a general preference for avoiding oral medications. From the before-and-after photos, diffuse thinning can be observed from the center of the crown, and the protocol yielded a noticeable increase in crown density by month six. No side effects or early shedding have been reported.

Case 2: Female (age unknown), about 5 months on topical minoxidil monotherapy (5% once nightly)

This user applied 5% topical minoxidil once nightly for about 5 months, using a liquid solution that she purchased over the counter after a telemedicine consult. She stated that she had AGA and did not note any other treatment. Based on both her comments and photos, she experienced marked improvement in hair density and coverage, stating that minoxidil “saved her hair” and that she wishes she had started earlier. She did not describe any notable early shedding, but noted dry scalp and some dandruff as potential side effects.

Case 3: Male (age unknown), 60 days on topical minoxidil monotherapy (5% foam nightly)

This Redditor applied 5% minoxidil foam once nightly before bed for two months without any concurrent treatment. He reports the typical amount applied daily as “one cap-full”, rinsed out the next morning. The user has Crohn’s disease with prior nutrient absorption issues, and chose to avoid ifnasteride due to side-effect concerns. He had about one year of noticeable thinning before starting. Upon starting minoxidil, shedding increased for the first two weeks, then eased. The first measurable improvement was visible by day 30, with clear density gains at day 60. The crown region improved the fastest, while hairline changes were slower.

Case 4: Female (age unknown), 1 year 5 months on topical minoxidil foam (5% once daily)

This user had AGA with prior telogen effluvium, reporting diffuse thinning along the part and temples and a reportedly high daily shedding. She began therapy with Rogaine Men’s Foam 5% once nightly, supported by Ketoconazole 2% shampoo once weekly. At 2 months of treatment, “peach fuzz”/baby hairs were visible at the hairline and temples. At 6 months, there was a noticeable density across the top with new hairs evident but still short. After 1 year and 5 months of therapy, she notes ongoing thickening and widespread new hair growth. She also reported that her shower shed decreased from ~70 hairs to ~10-15, with visual density improving at the part and temples. She reported a mild scalp itch at the start and subtle peach-fuzz on the upper lip and chin as side effects. 

Case 5: Male (age unknown), 2.5 months on topical minoxidil (5% liquid 1 mL twice daily)

This male user, likely with AGA, reported recession at the hairline and thinning at the crown after 2.5 months of using a Rogaine-style 5% liquid at 2 mL/day, without any concurrent DHT blocker. He experienced an early shedding phase ~1 month into treatment, which stabilized with continued use. He exhibited visible thickening at the hairline and crown by 2.5 months of therapy. He did not report any systemic or local side effects and plans to continue minoxidil while considering adding weekly microneedling and/or topical finasteride if progression resumes. 

Other Redditors have used combination treatments to further improve their hair regrowth. As you can see below, some of the results look dramatic.

Case 6: Male (age unknown), 3 months on topical combo (minoxidil 5% and finasteride 0.1% once nightly)

This user had thinning at the hairline and vertex areas of the scalp and began treatment to improve hair density and maintenance. He applied a single compounded solution (Novegrow) containing minoxidil 5% and finasteride 0.1%, once nightly, for three months before reporting on progress. Additionally, he dermarolled his scalp with a 0.5 mm needle twice weekly and supplemented with daily biotin and a multivitamin. He reported mild shedding in the first two weeks of therapy, and by month 3, he noted visible thickening and improved coverage. He did not report any side effects and added that the once-daily schedule was practical and helped with adherence.

Case 7: Male (25), 11 months on combination therapy (finasteride 1 mg daily and topical minoxidil foam 5% once daily)

This Redditor exhibited typical AGA with frontal recession and diffuse vertex thinning. His core regimen is oral finasteride 1 mg daily and minoxidil 5% foam (Kirkland) once daily. He noted he took regular ice/cold baths, ensured an increased water intake, engaged in exercise, avoided junk food, and did not smoke. He saw noticeable thickening from around 6 months after several shedding cycles. By month 11, he experienced substantial cosmetic improvement, with some commenters even comparing the results to transplant-level density. He did not report any adverse effects from finasteride or minoxidil, and subjectively felt less “brain fog” after starting finasteride.

Case 8: Male (37), 4 months on topical minoxidil 5% and topical finasteride 0.1% (1 mL nightly)

This male had crown-predominant thinning with a stable hairline at baseline. His core regimen is a single combined solution containing minoxidil 5% and finasteride 0.1%, applied to the crown only. He did not report any microneedling or supplementation. He reported that shedding began around week 3 and was “heavy” for approximately 4 weeks. The shedding tapered and largely stopped at the 2.5-month mark. By month 4, he achieved visible crown regrowth and thickening compared to the baseline, despite the application being limited to the crown. He perceived an increase in overall density and did not report any side effects.

Case 9: Male (34), about 12 months on topical finasteride 0.3% and minoxidil 6% (twice daily)

This male reported on his progress after using a combination of topical finasteride 0.3% and minoxidil 6% treatment twice daily for nearly one year. He first experienced hair thinning and hairline recession beginning in his late 20s. Alongside the topical treatments, he also applied a dermastamp at approximately 1.5 mm every 10 days. He reported significant shedding during the first two months of treatment along with mild chest tenderness in the first month, which resolved after temporarily halving the topical dose. He reported month-on-month thickening, with clear improvement by months 7-8 and robust density by the one-year mark.

Case 10: Male (22), 90 days on finasteride 1 mg and minoxidil 5% twice daily plus dermarolling

This user with early temple recession began a combination therapy of finasteride 1 mg oral daily, minoxidil 5% foam twice daily, and dermaoll 1.5 mm weekly. He experienced noticeable shedding at weeks 3-6 of therapy, and at the 90-day progress mark, he reported visible filling in of the temple and general thickening of the hair. He did not report any side effects and noted that pushing through the initial shedding phase was crucial to his progress thus far.

Probable Regrowth Timeline

Based on the available evidence, we have mapped out a likely regrowth timeline (although some may experience results faster or later).

Months 0-3: Initial shedding

• Temporary shedding may occur as follicles shift into a new growth phase.
• This usually resolves within the first 4-8 weeks.

Months 3-6: Early cosmetic improvements

• Early visible improvements, such as reduced shedding and appearance of fine new hairs, can be expected.
• Thicker, darker regrowth starts to become apparent for most users during this period.

Months 6-12: Peak cosmetic changes

• Cosmetic changes peak, with stronger hair, increased density, and the greatest coverage observed.
• This is the period of maximum regrowth for most individuals.

Months 12+: Plateau, maintenance, & slight regression

• Further gains plateau, with 5-year studies showing hair counts remaining above baseline –– but with some loss in “peak” results from year one. Continued daily use is needed to maintain improvements, as stopping treatment leads to a gradual reversal within a few months.

Safety and Side Effects

Local side effects are relatively common with topical minoxidil, especially with the liquid formulations. The principal culprits are propylene glycol and ethanol, which frequently cause redness, itching, dryness, and a dandruff-like scaling of the scalp.^[16]Makhlouf, A., Elnawawy, T. (2023). Hair regrowth boosting via minoxidil cubosomes: Formulation development, in vivo hair regrowth evaluation, histopathological examination and confocal laser … Continue reading Patients with sensitive skin are particularly prone to these adverse reactions and may experience contact dermatitis, which can make long-term use uncomfortable.

The foam formulation is generally better tolerated because it lacks propylene glycol. Most clinical trials and user surveys report fewer cases of scalp irritation, itching, or flaking with foam compared to the liquid version.^[17]Purnak, T., Senel, E., Sahin, C. (2011). Liquid formulation of minoxidil versus its foam formulation. Indian Journal of Dermatology. 56(4). 462. Available at: https://doi.org/10.4103/0019-5154.84714 

While systemic absorption of topical minoxidil is rare, some users may experience unwanted side effects such as dizziness and the growth of facial or body hair away from the application site. These effects are more likely if the medication is used excessively or applied to broken or abraded skin, which can increase absorption. We do not recommend using topical products if you have an inflammatory scalp condition – deal with that problem first, and then take a look at topical hair regrowth products.

Overall, when used as directed, topical minoxidil has a strong safety profile, with most side effects limited to mild local irritation.

Practical Takeaways

• Topical minoxidil is effective and well-established, but clinical results vary between individuals.
• Most patients achieve stabilization of hair loss with modest regrowth, though complete restoration is uncommon.
• Response depends partly on scalp sulfotransferase enzyme activity, which explains why some non-responders see little or no improvement.
• Best results come with consistent, long-term use and may be enhanced by adjuncts such as microneedling or topical retinoids to improve absorption and efficacy.

Final Thoughts

When evaluating minoxidil, it is important to recognize it as the most widely accessible and evidence-backed treatment for androgenetic alopecia. While outcomes can vary, most users see stabilization and modest regrowth rather than dramatic reversal. Success depends on realistic expectations, consistent use, and optimized regimens that may include adjunctive therapies. Applying a framework that emphasizes the likely trendline over anecdotal extremes can help you stay committed, avoid discouragement, and make informed decisions grounded in evidence and personal treatment goals.
