Does anyone else straighten?

I dislike my wavy hair and If I didn't straighten it Id look bad.  Just wondered if anyone else straightens their hair here and if sometimes it just doesnt straighten, no matter how much I try now adays it just keeps kicking out and going all frizzy and crappy looking. Why is this :(

Also how annoying is it for people to have naturally straight hair, and people who wash, dry, straighten their hair everyday yet it's still beautifull and shiny... I just want to beat them up.

I agree with what everyone else said.  I have somewhat wavy hair like you and it used to frustrate the hell out of me (still does sometimes) because I could never get it perfectly straight even with a straightening iron.  All an iron will do is damage the hair (I know people who straighten every single day and their hair, for the most part, looks awful and really unhealthy), and I know it seems like some people do everything to their hair and it still looks beautiful.  But the reality with about 99% of those people is that they're only putting gunky coned-up products in their hair to make it look wonderful and healthy.

You really just have to accept your hair the way it is, especially if you want to grow it longer.  Like ChelseaB said, consider an anti-frizz product.  Also, if you still want straight hair, there are other ways to get it besides an iron.  I use Paul Mitchell Straight Works gel sometimes on my hair when it's slightly damp- you only need a very small amount (about the size of a pea) and your hair will dry pretty straight.  And as long as you clarify regularly you should have no problem with build-up.

Oh, and one more thing: instead of trying to get it straight, why not try enhancing your waves?  Ever since I stopped fighting with my hair to be straight, I've experimented with different braids and sock-curls and it always comes out beautiful.

HTH,
