Should I cut my hair off in order for women to like me?

No, try putting a bag over your head when you go out in public...

If you like your hair long, then keep it that way! You don't have to cut it short to get people to like you. They should love you for who you are, and besides, there are a ton of hairstyles that involve longer hair; I'm certain you have not tried all of them. Maybe try slicking it back or parting it differently or brushing it (I know that sounds silly, but lots of guys don't even try brushing it and then wonder why it isn't an appealing look). Don't go out and get a perm, but before you change yourself for others and become pressured into something you don't really want to do, just change it around a bit, it might compliment your face a little nicer and you'll be surprised at the feedback.

If you DO end up cutting it as a last resort, maybe you won't dislike it all that much. However, I really don't suggest doing that JUST to get someone to date you, because if someone is dating you solely based on your haircut, they're probably not a keeper. Wear your hair however you are most confident, because radiating confidence is far more attractive than a haircut could be, and will probably improve your dating scene much more dramatically. Good luck, dude! :)

No. Wait for the right woman to come along who will accept you for you. If you cut your hair, you will be doing it to fit the approval of someone else. Fitting someone else's approval rate can cause you to lose your own identity. Good things happen in due time.

Keep it the way you want it. You'll meet a girl that actually likes you. Don't change for other people. You'll just end up unhappy

Don't change anything about yourself.

Be how you wish to be.

The right girl will come along.

No..if you like long hair and you cut it for someone else..you're doing a disservice to yourself.

Never change your style and what you like to suit others it will only backfire in the end. :)
