Topical finasteride that doesn't penetrate the skin could potentially treat hair loss without side effects. Current challenges include finding a formulation that remains on the scalp without increasing blood levels.
Tae147 has shared results of using pyrilutamide, a 5% concentration topical solution applied twice daily, in combination with minoxidil, to reduce scalp itchiness and hair shedding. Other users have shared their experiences with the treatment, as well as questions about its availability on the market.
The conversation discusses the potential benefits of creating a hydrophobic version of finasteride to reduce systemic side effects while maintaining scalp health. It compares this idea to fluridil, which is designed to be hydrophobic and has less systemic absorption.
