What I personally would do would be to buy another somewhat low cost PM (but not white body) Sam on eBay and steal it's head for the other one. That way you have a good condition mostly original white body as opposed to a mattel doll with a white body.

Then take the head with the terrible haircut and put it on the newer body and send THAT into the hospital.If you don't want 2 Sams, you could put it back on eBay to recoup your money, give it as a gift or some such.
