    Glossary Hair Follicle Bulge

    specific region housing stem cells for hair growth

    The hair follicle bulge is a specific region located in the outer root sheath of the hair follicle. It serves as a reservoir for stem cells that are crucial for hair growth and regeneration, as well as for repairing the skin after injury. This area is essential for the cyclical nature of hair growth and plays a significant role in conditions like alopecia.
