What if my donor area are not sufficient and don't have body hair. Is there any other option for a hair transplant?

You can have a combination of hair transplants with Scalp Micropigmentation and look like a gorilla. There are only a few medical groups that offer this combination (see web reference below and you will not have to shave your head for this to look good).

To transplant hair there needs to be donor hair available to take from somewhere. Therefore if you don't have donor hair, you can't do Hairtransplant.
