What is the other name given to the internal root sheath of hair?

The internal root sheath of hair is referred to as the internal epidermal root sheath. This sheath is a vital structure within the hair follicle, serving to support and shape the growing hair. It plays a key role in the hair growth process and is significant for maintaining the health of the hair shaft as it emerges through the skin.

The term "internal epidermal root sheath" specifically describes the layer of keratinized cells that closely surround the hair shaft, helping to anchor it within the follicle and guiding its growth. This name reflects its origin from the epidermis, which is the outer layer of skin.

Understanding the terminology behind hair follicle structures is essential for anyone studying waxing and hair removal techniques, as knowledge of hair anatomy is crucial for effective and safe practice.
