Yes, curd is excellent for hair. Curd has essential hair vitamins and nutrients like Vitamin B3, lactic acid, calcium and fatty acid. Curd's antimicrobial properties make it a mild cleansing agent that keeps dandruff and dry hair at bay. You can mix 2-3 tbsp of curd with 1 tbsp of lemon juice and apply it on your itchy, flaky scalp and rinse it off after 20-30 minutes.
