BMP4 and Nuclear Lamin C Orchestrate Expression of AHF/Trichohyalin Molecule, a Key Modulator of Keratin Intermediate Filaments in the Hair Follicle

PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

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.

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.

The conversation discusses potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

Rhamnose may promote hair growth and pigmentation, suggesting it as a potential hair loss treatment. The conversation discusses its potential alongside known treatments like Minoxidil, finasteride, and RU58841.

MCL-1 is important for hair follicle stem cell survival, but its impact on human hair regrowth is unclear. Minoxidil and finasteride are the main treatments, with doubts about new discoveries leading to effective human solutions soon.
