Epidermal Notch1 Recruits Innate Lymphoid Cells to Orchestrate Normal Skin Repair

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 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.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

A 23-year-old male is experiencing diffuse hair loss and miniaturization, possibly due to high IGE levels after using tofacitinib. He seeks advice and has not yet consulted a dermatologist.

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.

Mallia Aesthetics has developed MAL-838, a hormone-free product derived from sCD83, which stimulates hair growth without disrupting the skin microbiome. sCD83 promotes hair growth by activating hair follicles and preventing cell death, offering a localized treatment without systemic side effects.
