Long hair rocks. Even on gorgeous celebrities, long hair way outdoes short hair. Just look at celebs who have cut their hair.

Guys are as different as girls. I like long hair, and sorry, natural colours. For you, you need to express yourself as honestly as you like and are comfortable with. The right guy will fall in love with you as you are.
Long hair, my girlfriend cut her hair short and I only really like it bunned now. My girlfriends hair is dyed pink, only girls comment on her hair, as for me and other guys i talk about it, it doesn't appeal.
I felt the prettiest with shorter hair and I received more attention then than when I had long hair. It's how YOU perceive yourself. Most guys will say long hair, but the best kind of guy will sys whatever makes you feel your best. Pixies rock!
