Supplemental Information: Androgenic Alopecia – Crosstalk Between Cell Signal Transduction Pathways

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

The conversation discusses a new model for understanding androgenetic alopecia (AGA), linking it to dietary and lifestyle factors similar to PCOS, and highlighting the role of DHT, vascular damage, and inflammation. Treatments mentioned include Minoxidil, finasteride, and RU58841.

The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.

The conversation discusses using a multimodal approach to treat androgenic alopecia, including substances like gamma-linolenic acid, DHA, sulforaphane, melatonin, cetirizine, astaxanthin, fisetin, apigenin, curcumin, limonene, genistein, and berberine. Users also mention using ketoconazole, minoxidil, and low-level laser therapy (LLLT) as part of their hair loss treatment regimens.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.
