I personally don't find men attractive with long hair, however, I did quite fancy Anthony Kiedis from the Red Hot Chilli Peppers when he had long hair, but I guess it all comes down to personal taste.
I was a bit of a rock chick in my younger days and men with long hair were only fanciable when they wore tight ripped stone washed jeans, t-shirt, leather jacket and cowboy boots. Jon Bon Jovi, Axel Rose, Steve Tyler, David Coverdale. The list could go on and on lol. Still would do Steve Tyler though! That's my confession for the day ;-D
Ooh Lottie, I agree! Now that's one man that's got a nice bonce :P
Yep, long hair's nice as long as it's well kept as Weeal says, and not dyed. Men tend to have a habit of dying their hair a darker colour than their natural colour and they look like they've got a bald patch when the roots start coming through. Not a particularly attractive look :)
I thinks its a personal taste thing, I have never found long hair attractive in any men I have ever seen who sport it, that said there are plenty of female fans of long haired men.
