    Glossary Hair Follicle Pigmentation

    process of melanin deposition in hair shaft

    Hair follicle pigmentation refers to the process by which melanin, the natural pigment produced by specialized cells called melanocytes, is deposited in the hair shaft within the hair follicle. This pigmentation determines the color of the hair, ranging from black and brown to blonde and red, and can be influenced by genetic factors, hormonal changes, and aging.
