I personally don't comment on people's hair styles because sometimes you can offend them quite easily. The best way to find out if you have a sexy hair style or not is by asking the opposite sex.That's right. If you have a girlfriend, ask for her honest opinion to see what she has to say about it. Another way to find out if you have a sexy hairstyle is to see if you get any compliments when you go out. Usually if a girl starts flirting with you, they will tell you something about your appearance. And if they do talk about your hair means that you do have a sexy hairstyle.
Having something different than others doesn't make your hairstyle sexy. A sexy hairstyle is not what you like. It's what other people like. A sexy hairstyle will get you noticed, or even attract other opposite sex. If you're planning on going out, I would recommend that you do your hair and make them look good, because you never know who you're going to meet. So always look your best.
