What it is
A compounded topical formulation of finasteride in a vehicle such as alcohol, propylene glycol, or liposomal base, applied directly to the scalp.
How it works
Inhibits type II 5-alpha-reductase in scalp tissue, reducing local DHT. Some systemic absorption occurs with measurable serum levels, though typically lower than with oral administration.
Where it's used
Used off-label for androgenetic alopecia via compounding pharmacies and telehealth services, intended to reduce systemic exposure relative to oral dosing.
Regulatory status
Not FDA-approved as a topical formulation; available through compounding pharmacies.
Tracking it
Logging every administration of Topical Finasteride builds the record that makes patterns visible.
