CD98hc (SLC3A2) Regulation of Skin Homeostasis Wanes With Age

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

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 potential non-invasive topical treatment targeting the WNT Signaling Pathway for hair regeneration is being researched, with positive results on human hair follicle cells. Current effective treatments for hair loss include Minoxidil, finasteride, and hair transplantation.

SCUBE3, a protein linked to hair growth in moles, was discovered over 25 years ago and is being developed by Amplifica for potential hair loss treatment. Concerns exist about SCUBE3's association with cancer, as it is a protein that promotes cell growth, which could potentially trigger cancer development if used for hair growth therapy.

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.

Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.
