    GlossaryPigment Casts

    cylindrical structures in hair follicles containing melanin

    Pigment casts are cylindrical structures found in hair follicles that contain melanin, the pigment responsible for hair color. They can be observed under a microscope and are often associated with certain hair disorders, such as trichotillomania (hair-pulling disorder) or alopecia areata, where they indicate abnormal hair growth or damage.
