Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.
A user is experimenting with a DIY topical solution combining finasteride and minoxidil for hair loss, applying 0.5 mg of finasteride daily. Concerns include absorption issues, potential side effects, and product loss due to hair density, with some users suggesting oral intake for better results.
