Hair color is due to a substance called melanin, which produces the same skin color and changes from the intensity of sunlight received. Melanin is produced in melanocytes, which are cells found in hair follicles. These cells work together with keratinocytes which produce keratin with which the capillary structure is built, thus providing the shape and color of the hair.I
Melanocytes have a shorter life expectancy than keratinocytes, why hair loses its color before starting to fall as a result of age. This process starts with a reduction in melanin production, causing the hair to look gray, until the cells that produce finally die completely bleaching the hair.I
