cuticle of the inner root sheath

What is the Composition of the Cuticle of the Inner Root Sheath?

The cuticle of the inner root sheath is composed of overlapping, flat, and keratinized cells. These cells are rich in keratin, a type of protein that provides strength and resilience. The cells are oriented in a way that their free edges point downward, towards the base of the hair follicle. This arrangement is essential for anchoring the hair shaft within the follicle.
