Directions : How To Make Topical Finasteride

Note: these directions are customized based on the following inputs:

  • Your hair loss is diffuse, so you'll likely need ~2 mL of liquid daily to cover your balding areas.
  • You already bought 0.20% topical finasteride, and you plan on diluting it to 0.010%.
STEP #1: BUY TWO SOLVENT BOTTLES (60 mL PER BOTTLE)

A solvent is a liquid that helps to dissolve finasteride and carry the drug into the dermis of the skin. Think of your solvent as the "base" of your formulation.

For your convenience, here's a list of solvents you might consider (no affiliate links). These bottles come as 60 mL, but we need 120 mL of solvent. So, pick any solvent and buy two bottles.


After you've bought two of the same 60 mL solvent bottles, you can move onto step #2.
STEP #2: BUY A STORAGE BOTTLE (120 mL TOTAL)

In order to combine two 60 mL solvent bottles together, we'll need a bottle that has 120 mL of empty space and, preferably, a syringe for extraction. Here is an option (no affiliate links):


Once you have a 120 storage bottle, you can move onto step #3.
STEP #3: COMBINE SOLVENT BOTTLES TOGETHER
  1. Open both 60 mL solvent bottles
  2. Open your 120 mL storage bottle
  3. Add both 60 mL solvent bottles to the storage bottle
Once this is complete, you can move onto Step #4.
STEP #4: PREPARE YOUR 120 mL BOTTLE
  1. Open your 120 mL storage bottle
  2. Extract and discard 6.00 mL of liquid from the solvent. If necessary, use the following syringe:
This is to make room for the finasteride you'll be adding to your solvent bottle in step #5.
STEP #5: EXTRACT AND ADD YOUR TOPICAL FINASTERIDE TO THE STORAGE BOTTLE
  1. Open the bottle of your pre-purchased 0.20% topical finasteride.
  2. Extract 6.00 mL of liquid from your 0.20% topical finasteride. If necessary, use the following product:
  3. Add this liquid to your solvent bottle.
  4. Shake the bottle.
You've now made 0.010% topical finasteride. If using 2 mL daily, the bottle should last 60 days.
STEP #4: ADHERE TO USAGE PAREMETERS
  1. Apply 2 mL to thinning regions, once daily
  2. Let sit for 6-10 hours in the scalp before washing
  3. Respect how long it takes for finasteride to work: 6-24 months
Note: with this formulation, your total daily finasteride exposure is 0.2 mg. For reference, most men and women using oral finasteride take 1-5 mg daily.
