1- Hair transplantation:

Is removing thin strip of hair behind the head. This hair is genetically programmed to grow hair through out your lifetime. This strip is then sectioned into small grafts (mini grafts, micro grafts and one hair or follicular units) that are transplanted to bald or thinning areas of the head. This operation is done under local anesthesia. It lasts 4-5 hours. Several weeks after hair transplant, the transplanted hairs fall down. These hairs will regrow again and never fall down all lifetime. That will take at least 3 months to see this permanent hair. Which will grow 1 cm per month and it doesn't need any special care after the operation. You will go out without any bandage. You can begin shampooing your hair the day after the operation.
