The Use of Finasteride in the Treatment of Acne Vulgaris and Androgenetic Alopecia

A 19-year-old used a 0.01% topical finasteride formula, which unexpectedly lowered DHT levels significantly. They are considering reducing the dose further and exploring alternatives like ketoconazole shampoo, KX826, and CB to manage hair loss while minimizing systemic absorption.

Oral Dutasteride and topical Finasteride may have similar effects on scalp DHT, but topical Dutasteride might be less effective due to poor absorption. Combining oral Dutasteride with topical Finasteride could potentially enhance results by blocking DHT in both the scalp and serum.

Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.

Finasteride may cause acne for some users, possibly due to increased testosterone or estrogen levels. Zinc, gluconic acid, and B5 cream are suggested treatments for managing this acne.

Topical finasteride reduces scalp DHT effectively, with a suggested application of 1.5ml of 0.03% daily. It binds to scalp enzymes, potentially requiring daily or every other day application for sustained results.

Topical finasteride unexpectedly cleared the user's severe facial acne, which they attribute to reduced DHT levels. Another user shared a similar experience with topical minoxidil and oral finasteride, noting reduced acne and scarring.
