5-Alpha-Reductase Inhibitor Treatment for Frontal Fibrosing Alopecia: An Evidence-Based Treatment Update

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.

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

Finasteride helps with hair loss by lowering DHT levels in the scalp, which is more important than blood DHT levels. If finasteride is not effective, consulting a doctor or considering switching to dutasteride may be advisable.

A 25-year-old male has been using finasteride since October 2022 to combat diffuse thinning and hairline recession, experiencing initial shedding but later stabilization. He plans to add oral minoxidil to improve hair density and is open to trying dutasteride if necessary, with minimal side effects reported.

A 66-year-old male experienced significant hair regrowth using topical finasteride for 5 years and oral minoxidil for 3.5 years, with no side effects. He is now switching from finasteride to topical dutasteride 0.1% to potentially improve results further.
