Gray hair is hereditary. You get it from your children.How do gray hair start?
Hello! Gray hair comes from a number of things: age, heredity and shock to the follicles that can kill the melanin in the hair shaft.
I've heard from stress and age. Most doctors say stress causes it more than age. I guess life ain't easy huh?
There are other reasons: One is heredity: Family can make a big difference. I had a friend who got gray hair in middle school and another before they hit college. There are also medical conditions that can be linked with premature gray hair. A B-12 deficiency, a thyroid imbalance or even anemia can cause premature gray hair. Even in recent studies there is evidence that links gray hair to smoking. My advise for you is to love you're hair. We are not all blessed with great hair. In the long run you learn that it's yours and accept it even if it's gray.
Hair greying can be termed as one of the first visible signs of aging. Aging can show itself no better than expressing by the hair turning grey. Apart from the aging factor, premature hair greying can slowly banish your youthfulness. In that aspect hair greying is definitely a cause to worry. Here are some useful tips to treat your grey hair





What causes grey hair?





Intervening grey strands in your beautiful tresses is due to the cessation of colour pigment (melanin) in hair follicle. Pigment cells that are present at the base of the hair follicle stop producing pigment, which leads to lose of original hair colour. Melanocytes are the cells that produce melanin, which is responsible for the colour of the body and hair. With aging, melanocytes lose their ability in producing pigments, which leads to greying.





Physical or mental stress, malnutrition and constant worrying are some of the causes for premature greying. Apart from all this, genetics play an important role in hair greying. If your parents or your grandparents were victims of premature hair greying there are ample chances for your hair to go grey prematurely.





Washing hair in hot water, drying hair using an electric dryer and an unclean scalp can also cause premature greying.
