What it is

Finasteride is a pharmaceutical active, a 5-alpha reductase inhibitor used medically for androgenetic alopecia and prostate conditions. It is a prescription medicine, not a cosmetic ingredient.

What it does

Medically it lowers the conversion of testosterone to DHT. In this catalogue it is flagged for expert review rather than cosmetic grading, and no cosmetic benefit is claimed here.

Typical use

It is used under medical supervision, most familiarly as an oral prescription; it is not a general cosmetic formulation ingredient.

Safety

Graded mid risk and flagged as a pharmaceutical active requiring professional oversight. Suitability, dosing and possible side effects should be discussed with a qualified healthcare provider. This entry is general information and explicitly not medical advice.

Why we grade it Mid: Mid risk - functional/OTC-type active rather than a standard cosmetic ingredient; graded mid on an EWG-style basis. Informational only, not medical advice.
