My hair actually curls and frizzes in the back, waves on the side and get's superbly curly or straight in the front depending on how it feels. My hair is straight when it's wet until I run my fingers threw it. And then it curls. You have nothing to worry about! Hair is just a douchebag one verybody Lol
I have this awkward frizzy wavy hair. :( Which leads me to putting it up most of the time. Unless I shower, in which case my hair does dry really curly. If I brush it, it gets all wavy and crap.
It depends on your hair, really. I got a perm to make my hair completely curly but before I had naturally wavy hair. Before my perm my hair straightened as it dried and now it curls as it dries.
Personal tip: if your hair holds curl really well don't get a perm, it never goes away like it's supposed to.
My hair used to be straight and now it's curly and wavy too. And it is definitely not curly when wet. The hell? My hair curls as it dries too. Your friends are on crack.
