Graying of hair is a natural process that happens with increasing age, but if the hair starts graying before the age of 35, it is termed as premature graying that occurs due to the aggravation of Pitta dosha. Excessive intake of tea, coffee, alcohol, meat, fried, oily, greasy, spicy, sour, and acidic foods increases pitta and leads to graying prematurely.
