Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.

Gamma-rays exposure during the resting phase of hair growth can damage hair regeneration and color in mice.

Intense pulsed light treatment mainly damages pigmented hair parts but spares stem cells, allowing hair to regrow.

FUE can be successfully done on African-American hair by using larger punch tools and careful techniques to reduce hair damage.

The document concludes that recent studies help tell apart desmoplastic trichoepitheliomas from other skin tumors, but more research is needed for clear differentiation.

Antibiotics might affect hair growth by changing the bacteria in hair follicles.

Inositol and arginine solutions improve hair follicle health and turnover.

The new powered hair transplant method is faster and damages fewer grafts than the manual technique.

GRK2 is essential for healthy hair follicle function, and its absence can lead to hair loss and cysts.

Blocking both main energy pathways can stop hair follicle stem cell-induced skin cancer growth.

Higher fluence in hair removal damages hair follicles more, while lower fluence mimics natural hair regression, with long-term IPL treatments effectively reducing hair.

Light can activate hair growth through a pathway from the eyes to hair follicles.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.
