How can I help my boyfriend feel happier about himself again?

My boyfriend was in a car accident the day before Christmas eve- he was driving home from work when his car was hit by another car and it flipped over. He ended up breaking his right leg really badly (it needed surgery to pin it back together because it was broken in 4 places!) and shattering his hip. He is really lucky to be alive and we are both grateful for that :].

He is coming out of hospital in a few days but he is worried about the way he looks. The doctors had to shave the front part of his hair off so that they could stitch the cuts at the front of his head, and that alone has made him feel really self conscious. The whole right side of his face is badly grazed and still bright red cos the skin there doesn't seem to be healing at all at the moment. He had to have stitches along his upper lip, on his chin and down the left side of his nose. He has lots of cuts on his forehead and a pretty large cut on his left cheek too…

He is devestated at the way he looks, even though I keep telling him that it's not as bad as he thinks it is. I don't care what he looks like at all since I'm just glad to have him alive, but he is worried about what people will think when they look at him.

I presume there will be some pretty bad scarring though? Is there anything he can do to reduce the scarring? How can I make him feel better about himself?
