    GlossaryHair Follicle Stem Cells

    specialized cells in hair follicles that regenerate hair and skin

    Hair Follicle Stem Cells (HFSCs) are specialized cells located in the bulge region of hair follicles. They play a crucial role in the growth and regeneration of hair by periodically activating to produce new hair shafts and contribute to the repair of skin injuries. These cells have the unique ability to self-renew and differentiate into various cell types, making them essential for maintaining healthy hair and skin.
