TLDR Finasteride, originally for prostate issues, also treats hair loss, similar to effects from certain plants.
Merck's drug finasteride, initially released as Proscar® for benign prostatic hypertrophy (BPH), was later marketed as Propecia® for male pattern baldness after users reported hair growth. This discovery was paralleled by ancient knowledge of similar effects from plants like nettle and saw palmetto. Research by Jean Wilson and Donald Coffey identified finasteride's mechanism as a reductase inhibitor, which was later found to be mimicked by these plants. Dennis Awang hypothesized that these plants shift androgen/estrogen ratios, similar to finasteride's action.
