    Glossary Hair Follicles

    small skin structures from which hair grows

    Hair follicles are small, tunnel-like structures in the skin from which hair grows. Each follicle anchors a single hair into the skin and is composed of several layers, including the bulb at the base where cells divide and grow to build the hair shaft. These structures also contain sebaceous glands that produce oil to condition the hair and skin.
