A Systematic Review of Topical Finasteride in the Treatment of Androgenetic Alopecia in Men and Women

A user shared their experience using topical finasteride for 6 months, showing a reduction in DHT levels but no visible improvement in hair loss. They are considering switching to oral finasteride for potentially better results.

Topical finasteride reduces scalp DHT, with some going systemic. Using 0.025% at 1ml per day can stabilize hair loss without side effects.

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.

The user experienced increased hair loss with topical finasteride and is considering switching to oral finasteride. Others shared mixed experiences, with some suggesting oral finasteride is more effective, while others noted individual results vary.

A 23-year-old male with slight hair thinning is using ketoconazole shampoo, biotin, zinc, magnesium, D3/K2, and has just started topical finasteride (0.0125%). He plans to add minoxidil (4.5%) with 17α-estradiol and is seeking advice on the effectiveness and side effects of these treatments, as well as the use of a dermaroller.

A 21-year-old experienced hormone changes after using self-made topical finasteride for hair loss, including a 20% decrease in DHT, a 47% increase in testosterone, and a 39% increase in estradiol. The user previously used minoxidil and microneedling but is now seeking ways to balance hormones, possibly through supplements or dosage adjustments.
