Frontal Fibrosing Alopecia: A Retrospective Review of 19 Patients Seen at Duke University

The conversation discusses that dutasteride may be more effective than finasteride for frontal hair loss due to higher 5ar Type 1 enzyme activity in that area. Some users question the validity of this information, while others confirm it with additional sources.

The conversation is about managing allopregnanolone deficiency caused by 5-alpha-reductase inhibitors like finasteride or dutasteride. Specific treatments discussed for hair loss include Minoxidil, finasteride, and RU58841.

Dutasteride 0.5 mg significantly reduces both scalp and hair follicle DHT, with a greater reduction in hair follicle DHT. The discussion questions which reduction is more important for androgenetic alopecia and diffuse thinning.

Switching from finasteride to dutasteride led to retrograde alopecia for some users, with mixed results on hair regrowth. Some experienced increased shedding, while others saw regrowth or no change.

The user experienced hairline recession after switching from finasteride to dutasteride and increasing the dosage. They plan to start using oral minoxidil and are advised to be patient as shedding is expected during the transition.

Topical dutasteride is suggested as a low side-effect treatment for hair loss, with a proposed dose of 0.025% 1ml/day. It is considered better than finasteride due to its even inhibition of DHT isoforms and lower systemic absorption.
