    protein crucial for hair follicle stem cell regulation

    Keratin 15 (K15) is a type of protein found in the hair follicles and skin, playing a crucial role in the structural integrity and function of these tissues. It is particularly important for the maintenance and regeneration of hair, as it is involved in the regulation of stem cells within the hair follicle, which are essential for hair growth and repair.
