2 things. I would guess that if the donor hair is coming from your brother or sister, you'd stand a better chance of the grafts not rejecting.
Speaking as someone who had transplants, but they ran out of donor hair before the job was done, I'd contemplated asking the doctor - and my sister, if they'd go for person to person job, as descibed. Of course I didn't do it, but I did think about it.
For your information, when they remove donor hair, they slice out a flap of scalp from the donor area, and suture the area back in place, minus the donor strip. The thing about this, is that it makes your face much, much tighter, and younger looking, as if you had a face lift. That is one of the great byproducts of this, that no one talks about.
Now to get a woman to give up donor hair in a place where it will NEVER be detected, and at the end of the surgery, she'd look 10-15 years younger, might not be such a hard sell.
But hypothetically, I think it could work with a brother or sister. It would be impossible to get a doctor to agree to it, I'm sure.
The next best thing would be to offer some guy who's doing life in prison, some cash or cigarettes, for his donor hair.
He'd never need it.
Just think of alll those guys in prison with all that hair, just going to waste. :roll:
