Investigations of 13 Genes in Non-Cicatricial Alopecia

Hair loss may be linked to the GPR133 receptor, independent of the androgen receptor pathway. Treatments like finasteride, dutasteride, minoxidil, RU58841, and KX-826 show varying results, with hair loss persisting due to high testosterone and GPR133's role.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.
