Flat iron every day

Does anybody know how bad it is for your hair to flat iron it every day? I have heard that it does a lot of damage, but I can't find much information to back that up.

I don't have to use a flat iron just because my hair is so straight already but I would have to think that the heat of the iron would not be good for your hair. Especially if you use it everyday.

I have very straight hair as well, so I very rarely use a flat iron. In fact, I don't even own one, my sister she does. I love having very straight hair, it saves a lot of trouble in the mornings!

I would think that if you used a good moisturizer in your hair you might not burn it as much or dry it out.

My hair is also straight so I have never used a flat iron. But using it everyday could very well dry your hair out.
