Men like change. Almost a third of men told Cosmo that they mind if a girl styles her hair the same way every day.
But they don't always notice change. Almost a fifth of men polled by the UK's Daily Mail say they rarely notice when a woman changes her hair.
They like it up and down. Long, short, braided, blonde or brunette, it's all in how you work it, according to Cosmo. 43 percent of guys said they love watching a girl put up her hair, while 37 percent said they like watching a girl let down her hair. 20 percent said both are "equally hot." It's the simple things.
