Why Does Hair Turn Gray
Gray hair is a topic which attracts a lot of questions, especially from children. If you too are curious to know why does hair turn gray, read on to find out the answer.

Some of you may find the above scenario a bit familiar. Although graying of hair is extremely common in middle-aged and elder people, some teenagers and youngsters also experience premature graying of hair. Well, let us look at certain hair color related basics before we move on to the answer to this question.

Each strand of hair basically consists of two parts:

- Hair root
Reasons for Gray Hair
Now that we know the biological principle behind graying of hair, let us have a look at the different factors that lead to graying.
- Genetics: Genes play a major role in determining hair characteristics, hair growth and hair color. If either or both of your parents (or even your grandparents) developed gray hair at a relatively young age, there are chances that you too can meet with the same fate. In such cases, there is really nothing that you can do about it. You can only accept it as a part of life and move on.
- Vitamin Deficiency: Graying of hair can happen if you have a severe deficiency of Vitamin B12. Other medical issues like anemia or thyroid problems are also known to result in graying of hair. Having a healthy diet is something that you can look at as a way of lessening this problem.
- Chemicals: Over-exposure to harmful chemicals and pollutants can sometimes contribute towards graying of hair. At the same time, continuous use of strong shampoos, chemical hair dyes, hair colors and other hair care products may lead to premature hair graying.
- Smoking: It has been medically proven that smoking has a direct impact on graying and hair loss. Tobacco, nicotine and other cigarette contents have adverse effects on the melanin-producing melanocytes which ultimately lead to graying of hair.
- Stress-related Reasons: People who have extremely hectic lives and are constantly under stress are also prone to graying. Maintaining a healthy work-life balance, getting adequate rest and enough sleep can help in eliminating this problem.
