The change in hair color is caused by the gradual decrease of pigmentation that best dye to color gray hair occurs when melanin gray hair women ceases to be produced in the hair root, and new hairs grow in without pigment.

If a person carries the brown allele, he will gray hair color have brown hair; otherwise, gray hair natural remedies he will be blonde. This also explains why two brown-haired parents can produce a grey gray hair remedies blonde-haired child. The other gene pair is a not-red/red pair, where the "not-red" hair color gray allele (which suppresses production of phaeomelanin) is dominant and the allele for herbs for gray hair red hair is recessive. Since the two gene pairs how to cover gray hair both govern hair color, a person with two copies of the red-haired allele will have red hair, but it vitamins gray hair color will be either auburn or bright reddish orange depending upon whether the first gene vitamins to stop gray hair pair gives a brown or blonde hair color add gloss to gray hair respectively. The recessive genes for both brown/blonde and red hair are found nearly exclusively best shampoo for gray hair in populations of Whites and Caucasians.There is also a black gene, usually related to darker skinned humans.
