Delta 5-3 Beta-Hydroxysteroid Dehydrogenase Activity in Sebaceous Glands of Scalp in Male-Pattern Baldness

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.

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

The conversation discusses the link between seborrheic dermatitis, acne, and male pattern baldness, suggesting that DHT may cause both skin conditions and hair loss. Treatments mentioned include RU58841, finasteride, dutasteride, minoxidil, Nizoral shampoo, and other topical anti-androgens.

An 18-year-old experiencing hair loss and seborrheic dermatitis has tried finasteride, dutasteride, and various shampoos without success. They are considering anti-androgens like RU58841 and KX-826 for oil control and dandruff reduction.

The reduction in scalp oiliness is likely due to finasteride reducing DHT levels and the use of ketoconazole shampoo. The combination of these treatments may have decreased sebum production.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.
