    Glossary Hair Root Sheath

    protective cell layer surrounding the hair follicle

    The hair root sheath is a protective layer of cells that surrounds the hair follicle, which is the part of the hair located beneath the skin. It consists of an inner and outer sheath that help support and nourish the growing hair, playing a crucial role in the hair growth cycle. This structure is essential for maintaining the health and integrity of the hair as it develops.
