Clinical Snippets: Stabilization of Vitamins C and E, Hedgehog Pathway Agonists, Atopic Dermatitis, Lentigo Maligna Melanoma, and Relaxin-Deficient Mice

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.

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.

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.

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
