Effect of Neurosteroid Dehydroepiandrosterone on the Higher Nervous Activity of Old Non-Human Primates

High DHEA levels may contribute to hair loss by increasing DHT in hair follicles, potentially explaining why finasteride is ineffective for some. Treatments like high-dose dutasteride and RU58841 are suggested, but the underlying cause, such as adrenal issues, should be investigated.

A 23-year-old male is considering starting Finasteride for hair loss after experiencing persistent shedding and hairline recession, with bloodwork showing normal testosterone levels but low DHEA-S and Vitamin D. He plans to discuss DHEA supplementation with his doctor and has already started Vitamin D supplementation.

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

The user is concerned about high estradiol and normal DHT levels after 6 months on finasteride and 4 months on weekly dutasteride, noticing hair thinning. They consider increasing dutasteride frequency and adding RU58841 to their regimen.

Epristeride is a selective 5 alpha reductase type 2 inhibitor that may reduce scalp DHT similarly to finasteride, with potentially fewer side effects. It is suggested that combining epristeride with finasteride or dutasteride could enhance hair loss treatment effectiveness.

17-alpha-estradiol may work for hair loss by inhibiting 5-alpha reductase, similar to finasteride. It might lower testosterone in the scalp, reducing DHT conversion.
