Can I just tell everyone that I sat here looking at the pictures of Viggo for a few minutes before posting?!?!? I looooooove that man, no matter what his hair looks like.

I agree with what so many others have said - depends on the guy and the quality of the hair. I love long and healthy hair on a guy if it suits him. Some can pull it off, some can't.
