I definitely understand what you're saying. I'm going to clarify something first so I don't seem hypocritical. I got my hair chemically straghtened a while back (twice in my life) because I had the world's frizziest hair. You could not walk close to me without sneezing from my puffy hair. So I got it chemically straightened. My hair has since grown straighter than before and I don't plan to straighten my hair again anytime soon. Just to clarify.
Now, to answer your question, I completely agree with you. I just don't understand if when people who have naturally curly hair straighten their hair everyday. And these people who I am talking about have beautiful curls; some even have ringlets. I can't imagine how much TIME it's got to take to straighten all that hair. I don't see the point. And then, once it gets wet, it's done for. AND you're right, it totally fries your hair. It's stupid and sad. And then there are the people with straight hair who think they need to straighten their hair. Sad, really.
Edit:
For those of your out there who enjoy straightening your hair everyday, I'm just wondering if you realize just how damaging it is to your hair...?
And also, those of you with lovely curls, why do you straighten your hair? No offense, but half the time, if your hair is curly, when you straighten it, it just looks frizzy.
