There is no benchmark age for hair to turn white. Hair color is drastically affected by bodily health status, ethnic heritage, diseased conditions, hormones and stress. Hair turned grey merely due to less or no production of melanin. Each hair has a separate melanin supply in the body. Medical Conditions�leading to gray hair- 1.Thyroid Disease: An underactive or overactive thyroid can affect the melanin production in the hair which can cause premature greying 2.B12 Deficiency: Deficiency of B12 has also been linked to premature greying of hair. 3. Vitiligo: Vitiligo is a disease that is caused when the pigment producing cells in your skin and hair are damaged. Once the cells in your scalp are damaged, melanin production is reduced� and hair begins to turn grey.
