Why do so many teens today flat iron their hair so much? Anyone else notice the epidemic?

Anbyone notice how obsessed people seem with straight hair. Everywhere I go, it seems somone has straightened hair, or is bashing curly hair. Don't get me wrong, all hair types are beautiful and unigue, but why are some people so compelled to waste two hours of their morning to have fried out hair? Sorry if this opinionated, but anyone else getting tired of the flat iron fad?
