As we grow old hair turns grey in color. Aging limits the generation of melanin pigment in the hair bulb that gradually results in grey hair. When the amount of melanin decreases rapidly, certain people suffer from early graying. Black tea with salt is one of the remedy to make grey hair black. Hairs near the temple portion turn to grey first, later covering the crown and then reaching the back of your head. Mix a tablespoon of table salt to a strong black tea. Apply this solution to your scalp and massage well for an hour and wash it off. This will help in turning grey hair black again.
