The butter made from cow's milk has the property to prevent premature greying of hair. A small roll may be taken internally and a little quantity may be massaged into the hair root twice a week. Ribbed gourd, known as torai in the vernacular, boiled in coconut oil is another effective remedy for premature greying of hair. Pieces of this vegetable should be dried in the shade. These dried pieces should be soaked in coconut oil and kept aside for three or four days. The oil should then be boiled until the solid is reduced to a blackened residue. This oil should be massaged into the scalp. It will help enrich the hair roots and restore pigment to the hair.
