    Glossary Hair Keratinocytes

    specialized cells in hair follicles producing structural protein keratin

    Hair keratinocytes are specialized cells found in the hair follicle that produce keratin, a protein that forms the structural foundation of hair. These cells play a crucial role in the growth and strength of hair, as they continuously divide and differentiate to form the hair shaft.
