The cells that impart color to the hair, called melanocytes, are the same cells that impart pigmentation to the skin. The melanocytes located in hair follicles are more sensitive to the aging process than those in the skin. Seek a fellowship-trained facial plastic surgeon if you have concerns about your hair.
Why Our Hair Turns Gray with Age
Dr. Jeffrey Harmon
Melanocytes in the Skin and Hair Follicle are Related but Behave Differently
Melanocytes in the skin and hair follicle are related to each other but behave differently where they reside. For example, melanocytes associated with hair follicles function with the hair cycle; that is, when the hair is in its growth stage, called anagen, it is producing the melanin that pigments the hair. However, when the hair is dormant (i.e., telogen phase) melanin is not produced. Melanin is always produced by melanocytes in normal skin.
The Number of Melanocytes in the Hair Follicles Decreases with Age
When melanocytes are lost in the hair follicle there is less melanin produced and less pigment in the hair. This is what leads to graying of the hair. This process tends to occur in the scalp earlier than in the beard and in body hair in men.
The average age of hair graying depends on an individual’s gender, race, and family history. For example, Caucasians tend to start graying the earliest, in their mid-30s. The cause of early graying is not yet clear, though it may have something to due with the production of inflammatory free radicals in the body, like what causes skin changes associated with aging, chronic sun exposure, and tobacco use.
