Napkin math: are we using 100x more topical finasteride than necessary? Finasteride/Dutasteride 4/26/2026
Topical finasteride concentrations are likely much higher than necessary for effective follicular DHT suppression, with current standards being 100-1000 times above the theoretical minimum. Lower concentrations (0.001-0.0025%) might still work locally while minimizing systemic exposure.

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.
community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)
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.
community to all people who cannot tolerate anti androgens (loe dose topical fin, pyrilutamide, CB) i am getting desperate, looking for a solution
The user tried Minoxidil without success, and Finasteride worked but caused sexual side effects even at a very low dose. They are seeking alternative treatments for hair loss as they cannot tolerate anti-androgens and are also in therapy for mental health.
community My derm said they came up with a new serum that is better then fin? What’s y’all’s thoughts
A new serum claims to enhance hair regrowth by amplifying oxygen delivery, improving the effectiveness of treatments like exosomes and peptides. Users are skeptical, questioning its efficacy compared to established treatments like Minoxidil and Finasteride.
community My Theory Regarding a Cause and Cure for Androgenetic Alopecia
Hair loss theory suggests imbalance between Vitamin D Receptor (VDR) and Androgen Receptor (AR) activation. Proposed treatment includes upregulating VDR, downregulating AR, and improving mitochondrial health.
