    GlossaryHair Follicle Cells (Follicular Cells)

    specialized cells responsible for hair growth and regeneration

    Hair follicle cells, also known as follicular cells, are specialized cells located within the hair follicle, the skin structure responsible for hair growth. These cells play a crucial role in the hair growth cycle, including the phases of growth (anagen), regression (catagen), and rest (telogen). They are involved in the production of keratin, the protein that makes up hair, and are essential for the regeneration and repair of hair.
