Hair requires a good number of vitamins and minerals too. Vitamin A encourages healthy production of sebum in the scalp and also helps in hair growth. It is found in dark leafy green vegetables, sweet red peppers, mango, papaya etc. Vitamin B12 found in milk, and milk products, beans etc. is useful for hair growth. Biotin is very important for hair health. A deficiency of biotin can cause hair fall and hair thinning. So, if you are suffering from hair fall, include foods like dairy products, nuts, green vegetables e.g. cabbage that are rich source of biotin in your regular diet.
