Human Dermal Fibroblasts and Mast Cell Populations Are Altered in Hidradenitis Suppurativa, With Epithelial-Mesenchymal-Transition Signals Ameliorated by Spleen Tyrosine Kinase Antagonism

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

Gut microbiota significantly influences androgen metabolism, impacting hair loss treatments like finasteride. Probiotics, dietary changes, and fecal microbiota transplants may help manage DHT levels and improve hair health.

Adipose-derived stem cell secretome showed significant improvement in hair density and growth, especially when combined with minoxidil, suggesting a synergistic effect. The study had limitations, including a small sample size and potential bias.

Hair follicles cannot be desensitized to DHT like allergies; treatments focus on reducing DHT levels or blocking its effects using methods like finasteride, GT20029, or PROTACs. Topical treatments like ceterizine and BPA application are also mentioned.

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.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.
