The hair has a tendency to lose its natural colour with advancing age and turn grey, but premature greying is a morbid condition and it makes even the young look older. The hair is an appendage of the skin. It is composed of the same kinds of cells as are found in the outer layer of the skin, which is known as the epidermis. Hair grows from hair follicles which are deep recesses in the epidermis. The sebaceous glands of the scalp secrete an oily substance called sebum, which is the source of nutrition, lustre, and blackness of the hair. The hair cannot be fed externally, for such nourishment, as the scalp requires, must come to it from the bloodstream.

Causes of Premature Greying of Hair
Faulty diet, Mental worries and lack of vitaminsA faulty diet and mental worries are the two primary causes of premature greying of hair. Lack of some of the B vitamins, iron, copper, and iodine in the daily diet is said to be a contributory factor. Mental worries produce extraordinary tension in the skin of the scalp; this interferes with the supply of vital nutrition necessary for the health of the hair.
