Mitotic cells are primarily found in the matrix of the hair follicle. The matrix is located at the base of the hair follicle, right above the dermal papilla, and is where the actual cell division occurs. This part of the follicle contains rapidly dividing keratinocytes that contribute to hair growth by pushing older cells upward, which eventually keratinize and form the hair shaft.

The matrix is critical in the hair growth cycle because it produces new hair cells that lead to the formation of the hair shaft. As these cells proliferate and differentiate, they contribute to the overall structure and health of the hair. The bulb houses the matrix and acts as the site where the new hair is generated.

In contrast, while the follicle itself is crucial for hair development, it contains various structures beyond just the matrix, including the outer and inner root sheaths. The hair shaft, on the other hand, is formed of hardened and keratinized cells that have already completed their mitotic division and are no longer actively growing. Thus, the correct understanding of where mitotic activity primarily occurs helps in grasping the fundamental processes of hair growth and development.
