Hair has a tendency to lose its natural tint with age. A white hair is produced by the formation of numerous air spaces throughout the cells composing it. Greying of the hair in old age is natural but premature greying of the hair is a morbid condition. The causative factors ioclude certain diseases like chronic colds, sinusitis, and a constitution given to excessive passion and worry. Persons who are given to washing their hair with hot water are more prone to suffer from premature greying of hair than others.
