Premature Gray Hair Problem

It is worst to have premature gray hair. Many people get this even at the age of 18 and still younger. Humourously some people say, the minute you think that such gray hair disease "Gravess' Disease" or Hyperthyroid exists in the worl, you may get it. It is such a common thing and many people may get it. A group of scientists and researchers worked on this problem and found that this premature hair graying is because of reduced bone mineral density. This appearrance is more in above 40 year old people, but we may not call there as premature gray hair. It is a wise thing to check bone density if you have premature gray hair.
