What Is Responsible For The Color Of Gray Hair

Grey hair is more obvious in people with darker hair because it stands out but people with naturally light hair are just as likely to go grey.

When graying hair is caused by medical conditions successfully treating the disorder usually results in the hair returning to its normal color. Examples of folate rich foods include beans asparagus leafy greens and citrus fruits. As we age our hair stops generating melanin which is what gives our hair color boatman adds that when we go gray and the shade of gray we go is largely determined by genetics. Para amino benzoic acid paba and pantothenic acid are part of the b vitamin group and some believe taking them together can help reverse graying hair.

Melanocortin 1 receptor mc1r is the gene responsible for hair color determination. A better understanding of mc1r and other genes will go a long way to help in explaining the variation in skin and hair color in human populations. Small amounts of pigment in the medulla all skin is the same in terms of degree of keratinization blood supply and nerve supply. It is found on the surface of melanocytes and also in other cells and play a role in the immune function in humans.

Deficiency of vitamin b12 is quite commonly mentioned cause of grey hair. Vitamin deficiency graying hair can also be caused by a deficiency in vitamin b 9 commonly known as folic acid. When the melanocyte cells stop producing melanin completely hair turns white. B vitamins are essential to the hair.

Throughout our lifetime our melanocytes continue to inject pigment into our hair s keratin giving it color however after a certain amount of years of producing our melanocytes go on strike so to speak and stop making as much melanin which causes grey hair or make no melanin at all which causes white hair. In some cases grey hair may be caused by a deficiency of b12 or a thyroid imbalance. Hair turns gray when the cells that produce melanin the melanocyte stem cells begin to die. The genetic factors responsible for pigmentary variations needs further investigation.

Vitamin b 12 vitamin b 12 deficiency is one of the most common causes of prematurely graying hair. In case this vitamin was responsible for premature greying it can be reversed back once levels of vitamin b12 in the body are increased.
