Topical finasteride is the same DHT-blocking active as the familiar pill, compounded into a solution or spray applied to the scalp. The idea behind it: deliver the medicine where the hair is and potentially limit how much circulates through the rest of the body.
It's a compounded, prescription-only formulation - not a separate FDA-approved product - so quality depends on the pharmacy and the provider prescribing it. Background on the oral version is in does finasteride work.
