Genome-Wide Association Study and Transcriptome Differential Expression Analysis of the Feather Rate in Shouguang Chickens

Hair loss treatments like Minoxidil, finasteride, and potential mRNA therapies are discussed. There is skepticism about targeting specific genes due to the complex genetic nature of hair loss.

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

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.

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.

Cantonese men may experience earlier and faster hair loss due to factors like genetics, stress, late nights, and oily scalps. The region has a significant hair-loss market, and China has a "baldness map" highlighting this pattern.

KX-826 Phase II results show that a 0.5% concentration performs better than 1% for treating male pattern baldness. Concerns about receptor upregulation from long-term DHT antagonism were mentioned.
