Does anyone know good permanent hair straightening products?

I wanted to permanently straighten my hair, but the lady said i can't go in the pool because the chlorine and shock would fry it. Does anyone know some safe products that will straighten my hair without frying it? My hair is thick and really curly/wavy and almost every morning i have to straighten it, which is very time consuming and damaging to my hair. Thanks so much!Does anyone know good permanent hair straightening products?
I also have really wavy hair and I have had my hair relaxed and rebonded before quite a few times. I recommend that you just keep straighting it since to get it permanently straightened costs a lot sometimes plus, it doesn't really permanently straighten your hair. Your hair will be less wavy and curly for a few months, but it won't be straight like someone who has naturally straight hair. When I had mine rebonded, I still had to use a flat iron in the morning before school, just not as much though.Does anyone know good permanent hair straightening products?
Overall, straightening hair is hundred times less damaging to your hair than some chemicals, so all I say is, keep toasting it ;)
