Role of the Notch Ligand Delta1 in Embryonic and Adult Mouse Epidermis

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.

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.

Applying Epidermal Growth Factor (EGF) topically may improve skin and potentially promote scalp health and hair growth, especially after microneedling. The user shares their positive experience with EGF and provides a product link.

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.

The conversation is about hair regrowth using high-dose dutasteride, oral minoxidil, and microneedling. Users discuss seeing tiny hairs and hope they will become terminal, with advice to use derma rolling weekly for better results.

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.
