Cosmetics Formulation Development

hello everyone I just joined for the first time. I'm also treating thinning hair with oral finasteride and minoxidil topical. Now I want to make finasteride 1% topical, but I don't know how to do it. Well, I don't want to buy it at the hospital. Waste, I tried mixing it with minoxidil and it turned out that the drug was precipitated. So I would like to ask someone who has knowledge of chemistry a bit.

I understand that the company does not sell drugs. may not recommend to you But if in terms of cosmetic ingredients, there is Redensyl that the test results are 2 times better than minoxidil.

misix24 I would like to know how much alcohol, distilled water and what solvent do I need?
