Has there been any update or progress on the 3-alpha hydroxysteroid dehydrogenase hypothesis? 7/17/2026
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.
