Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Lactate production is important for activating hair growth stem cells.

Stem cell niches support, regulate, and coordinate stem cell functions.

Stem cell self-renewal is complex and needs more research for full understanding.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
