Effect of Dutasteride 0.5 mg/day in Men with Androgenetic Alopecia Recalcitrant to Finasteride

A 27-year-old male physician improved hair density using minoxidil 5% foam and finasteride 1mg every other day, with initial sexual side effects that subsided. He recommends trying finasteride for a year but warns against dutasteride due to potential liver effects.

Topical dutasteride with microneedling is effective for androgenetic alopecia, improving hair thickness and density. Further research is needed to confirm long-term efficacy.

Topical dutasteride, particularly at 0.05%, shows greater hair density improvement than oral finasteride over 24 weeks, though hair thickness gains are similar. Some users report side effects with topical treatments, but others find them effective for maintaining hair without significant systemic absorption.

Monthly microneedling combined with low-dose topical dutasteride shows promising results for hair density and thickness with minimal side effects, especially in the frontal area. Despite its effectiveness, it is not widely discussed or used due to availability and cost concerns.

A 23-year-old discusses their hair loss treatment using finasteride, dutasteride, oral and topical minoxidil, and topical tretinoin under medical supervision. They stress stabilizing hair loss before a hair transplant and plan to continue the regimen for at least 18 months.

Switching from finasteride to dutasteride can worsen hairlines for some, as experienced by the original poster. Finasteride worked better for them, and they suggest returning to it if dutasteride causes hair loss.
