Hair is curly on the sides of the head wavy at the bottom and then straight on the top Help?

If your problem is that you want your hair to look all the same, I would say that you should just be happy with being unique, but if you want your hair to be all the same here is what you can do:

Get a straightener and straighten the hair on the sides of your head and at the bottom

Curl all your hair, and then mess it up. Girls love guys with messy hair and guys love girls with naturally-beautiful kind of hair.
