Wet to dry is horrible for your hair. Make sure you get a ceramic hair straightener it's best for your hair and they work really well. Also alway put a heat protectant on your air before you apply any heat.
I second wet to dry it's amazing I have very unruly hair mySelf
Got mine at Wal-Mart.. I dnt straighten my hair anymore cuz I'm lazy but wen I did I liked it..
Try Sally's beauty store or walgreens
I have a Remington wet 2 straight that works awesome. It was under $50, I can't remember how much it was exactly because I've had it for going on 8 years.
