New treatments for skin and hair repair show promise, but further improvements are needed.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

Type 1 Diabetes prevents hair growth by causing cell death in hair follicles.

Exosomes show promise for improving wound healing, reducing aging signs, preventing hair loss, and lightening skin but require more research and better production methods.

Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.

The new microwell device helps grow more hair stem cells that can regenerate hair.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.
