What is topical finasteride?

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.

Topical finasteride vs the pill: what's the difference?

The pill has decades of use and the deepest evidence base; the topical is the newer route, typically chosen by men who want a DHT blocker but prefer applying it locally - often after discussing side-effect concerns with a provider (see our finasteride side effects guide). Effectiveness and side-effect trade-offs are individual, and this is exactly the conversation to have with the licensed provider who evaluates you - not a decision to make from marketing pages.

Who sells topical finasteride online?

The verified option in our ranking is PeterMD's Follicure RX: a 3-in-1 topical spray combining minoxidil, finasteride and ketoconazole at $70 per 50mL bottle (regularly $80; a two-pack runs $140), prescribed after a licensed-provider review. If you want a stronger compounded topical without finasteride specifically, Happy Head's Custom Topical runs up to 8% minoxidil with dutasteride 0.3% at $49 for the first order (regularly $89/month). Prices as published in August 2026.

Is topical finasteride right for you?

Reasonable candidates: men who want a DHT blocker in their plan but prefer a scalp-applied route, and men already using a topical who'd rather combine actives in one application than add a pill. The wrong reason: expecting it to be a side-effect-free version of the pill - it's still finasteride, and a licensed provider should walk you through what's known.
