Picture of Premature Gray Hair

Hair grays prematurely largely due to genetic reasons. Hair derives its color from the pigment melanin. A decrease in melanin produces gray hair. Stress, illness, and trauma may also increase the risk of premature gray hair. A deficiency in vitamin B12 may also contribute to the condition in rare cases.
