How to scrunch straight hair!?

Get a perm. My hair is the same and it would never curl. So i got a loose perm which is like beach waves and I love it! All i do is get a shower and put moose or gel in it and it dries sooooooo pretty! I would def recommend it! It does damage your hair a little but not much. It will last 6 months to a year! and you can also still straighten it!
