Bone Morphogenetic Protein Signaling Controls Hair Pigmentation Through Cross-Talk With the Melanocortin Receptor-1 Pathway

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

The conversation discusses hair loss linked to BDNF-increasing nootropics like Semax and Lions Mane. Suggested topical treatments include capsaicin, beta-glucan, and ginseng to counteract TGF-B activation.

BPC-157 may promote hair growth by increasing angiogenesis, similar to how Minoxidil works, though no direct research confirms this yet. Users report combining BPC-157 with Minoxidil and finasteride for better results, but concerns about long-term safety exist.

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.

ABS-201 may block prolactin receptors in hair, potentially reducing androgen receptors and affecting hair loss. It could also aid collagen synthesis and stem cell pathways, similar to GHK-Cu.
