Does hair straightening cause damage even if used correctly?

[Scuderia]

I tried to find information to see if hair straightening is good or not.

I plan to use GHD Eclipse

First of all, do I need to straighten my hair every day if I wash my hair every day?
And if I use it correctly, will it still damage my hair?

I would try not to wash and straighten your hair everyday as that will really damage it. You can use heat protecter sprays to help but it will still cause damage x
