Hair Color is made of Melanin. Melanocytes cluster in the center of the hair strand giving us hair color. A big reason for a change in hair texture when hair turns grey is the lack of structure from the absence of melanin. Melanin is produced by pigment cells, which are created in the hair follicle. The base of the hair follicle is surrounded by the hair matrix, this matrix is where color and hair cells form. Melanin is either made of Eumelanin, Pheomelanin or a unique formula of both. Eumelanin is Darker (brown / black), Pheomelanin is Lighter (orange / red), Eumelanin is not only darker, but typically a larger hair strand.
