What is the Function of the Cuticle of the Inner Root Sheath?
The primary function of the cuticle of the inner root sheath is to assist in the proper formation and growth of the hair shaft. It ensures that the hair remains anchored within the follicle during its growth phase. Additionally, it provides a smooth interface between the hair shaft and the inner root sheath, which facilitates the upward movement of the hair as it grows. The cuticle of the IRS also plays a role in protecting the hair shaft from mechanical damage and environmental stressors.
