    Glossary Follicular Keratinocytes

    specialized cells in hair follicles producing keratin for hair

    Follicular keratinocytes are specialized cells found in hair follicles, the structures in the skin that produce hair. These cells are responsible for producing keratin, a protein that forms the structural foundation of hair. They play a crucial role in the growth and health of hair by continuously dividing and differentiating to form the hair shaft.
