The Investigation of Selective Sphingosine-1 Phosphate Receptor 1 and 4 Modulator to Treat Alopecia Areata Mouse Model

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.

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.

Exploring hair loss treatments beyond DHT, including Minoxidil, pyruvate, Gt20029 targeting androgen receptors, and vasodilators. Other options like Kx826, adenosine signaling, growth factor topicals, and microneedling are also discussed.

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.

A South Korean company, Therazyne, has developed a promising hair loss treatment using a WNT chain surrogate that binds to Frizzled 7, with human follicle testing expected soon. Current treatments like minoxidil and finasteride are not seen as cures, and while optimism exists for future solutions like PP405, approval processes are lengthy.
