I used to have really long and pretty hair, but then I started straightening it a lot. It got really burned. I went to the hairstylist and she cut it really short, and I don't like it like this. How could I get it to grow longer? Any tips?

Take good care of your hair. Do not straighten, color, or blow dry it. Use a good shampoo and conditioner. If you eat well and take vitamins, even better. Also, don't forget to get a trim often.
