Is there something wrong with my straightener/ the way i straighten my hair?

When you go get your hair cut, if it's not already cut it to shoulder length or a little bit under your shoulders. Get the hair stylist to thin out your hair, he/she will know what it means. Use straightening shampoos like Herbal Essences Dangerously Straight, I think that's the name. When you straighten your hair you will put the straightener at the top of the piece of hair and then have a comb underneath. You will comb down and move the straightener down as you are combing. Straighten small pieces instead of large pieces.
