All of us have a hereditarily and genetically determined time when we will get gray hair. Even though nothing can prevent hair from becoming gray, but still there are some situations that can cause hair to gray earlier or more speedily than usual. Premature Graying of Hair is a miserable situation where the hair of teenagers, turn gray before age. Graying of hair is a normal procedure. Hair turns slowly gray because of decrease in the production of melanin pigment in the hair tuber, as we grow old. You will notice the initially gray haring starts near the temples, then to the top and then at the backside of head. Premature graying is a result of quick decline in melanin.
Hair grows in phases, with a definite proportion of hair either growing or resting at any one time. The hair follicles, which are the little bags under the skin where hair is shaped out of skin, they also have pigment known as melanin.
When the body stops generating pigments, the hair turn colorless (or gray), and finally turns white. Mixed with darker hair, this make a look generally related with gray. An actual gray hair may be an effect of pigment dilution. Gray hair growth in the facial hair and mustache may also initiate quite early, while gray hair on the chest and pubic area usually takes some years after start of gray hair on the scalp.
