Clinical Dose Ranging Studies with Finasteride, a Type 2 5α-Reductase Inhibitor, in Men with Male Pattern Hair Loss

A 22-year-old male experiencing diffuse hair thinning has been using finasteride, initially at 0.5mg and then 1mg daily, but sees no improvement. Despite correcting a vitamin D deficiency and noticing some new hair growth, he questions the effectiveness of finasteride.

The efficacy of low doses of finasteride to reduce scalp DHT, and whether studies showing a 61% reduction are reflected in actual results. Replies discussed hair growth as an unintended consequence of minoxidil and finasteride use, as well as self-selective bias, potential side effects, and that studies measure effectiveness by hair count changes rather than DHT inhibition.

Epristeride is a selective 5 alpha reductase type 2 inhibitor that may reduce scalp DHT similarly to finasteride, with potentially fewer side effects. It is suggested that combining epristeride with finasteride or dutasteride could enhance hair loss treatment effectiveness.

Finasteride is effective for treating male pattern baldness (MPB) with minimal side effects, and topical finasteride is similarly effective. Dutasteride is also effective but less understood, and Minoxidil is less effective than Finasteride.

Finasteride reduces scalp DHT significantly even at low doses, with 0.2 mg reducing it by about 55%, but higher doses like 1 mg and 5 mg offer only marginally more reduction. Users discuss side effects, with some experiencing none and others reporting issues like low libido, and they also mention using other treatments like minoxidil and dutasteride.

Hair loss treatments, specifically, discussing the effectiveness and side effects of finasteride, minoxidil, and RU58841 in various microdoses. It also includes an updated graph which provides information on how different doses affect DHT levels, scalp skin and serum androgen levels, as well as hair count.
