region in hair follicle housing stem cells for growth
The hair bulge is a region located in the outer root sheath of the hair follicle, near the base of the hair shaft. It serves as a reservoir for stem cells that are crucial for hair growth and regeneration, as well as for the repair of the skin after injury. This area plays a significant role in the hair growth cycle and is a key focus in research on hair loss and regenerative medicine.
