Platelet-rich plasma can potentially promote hair growth by stimulating cell growth and increasing certain proteins.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

Middle-aged women with chronic telogen effluvium experience increased hair shedding but usually don't get significantly thinner hair.
