Cutaneous Hydroxysteroid Dehydrogenases and Rat Hair Cycle

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 conversation discusses the molecular structures of compounds that reduce DHT levels, including finasteride and Ashwagandha. It explores the potential of using Ashwagandha topically as a 5a reductase inhibitor.

Progesterone, hydrocortisone butyrate, and estrone base are discussed as treatments for hair loss. Topical progesterone and dutasteride are suggested to potentially reverse androgenic alopecia.

The user experienced high estradiol levels and side effects after stopping finasteride and is concerned about whether these hormonal imbalances are temporary. They are seeking advice on reversing the condition without starting new treatments due to hypersensitivity to finasteride.

The user has been using oral minoxidil and dutasteride for hair loss without success and is considering adding topical 17α-estradiol, Pyrilutamide, Clascoterone, or cetirizine. They have confirmed low serum DHT levels and are exploring additional treatments due to genetic sensitivity to DHT and prostaglandin D2.

The conversation discusses using estradiol and its derivatives for hair loss without causing feminization. Users mention alternatives like alfatradiol, topical 17b-Estradiol, and DIM (Diindolylmethane).
