Grey hair is becoming common nowadays and no one are able to get rid of this. Through the natural process of graying of hair is observed for long, however, these days this phenomenon is becoming more common in earlier ages and even in teenagers its frequency is increasing at an alarming rate.
The causes of grey hair is still a debate and new research insights are being harvested to reach a to final conclusion to address this condition. Genetics, vitamins, habits of smoking and lack of proper diet are responsible for grey hair causes.
The main reason for the grey hair is genetic i.e. the offspring is more prone to have grey hair earlier in life if its parent has the grey hair at early ages. Only not that the scientists discovered that our hair turns gray if the overload of melanin and hydrogen peroxide is found in the body genetically.
Hair goes gray when color-producing cells stop producing pigment, says Jeffrey Benabio, MD, a dermatologist at Kaiser Permanente in San Diego. Naturally occurring hydrogen peroxide can also build up in the hair, bleaching the color.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and African-Americans in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
A white person is considered to be prematurely gray if his or her hair turns gray by age 20; gray before 30 is early for African-Americans.
