Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Stem cells can help regenerate hair follicles.

Injecting a mix of human skin and hair cells into mice can grow new hair.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Polycomb Repressive Complex 2 is not needed for hair regeneration.

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.

Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.
