If you have lost so much hair due to jaundice, or any other disease, it is important for you to know that you must give your body at least a year to recoup from the illness. The body always takes time to recover completely and return to normal functioning. After about a year, for most part, you will have recovered a sufficient amount of hair, if not all of it. But to help the process along also, you can follow some simple remedies that will help you. Massage your scalp with warm almond or olive oil at night and wash it off the next morning. Do this at least twice a week. The oil will encourage hair growth. To encourage new hair growth, you can make a mix of fresh onion juice and egg yolks and apply this to your hair and scalp. Wash with a mild shampoo after about an hour of application.
