hey there!
I have a T3 tourmaline wet to dry. I suppose that with any heat added to hair, it would be somewhat damaging, so theres always a risk. I think you would have better results, since you're a 2B and i'm a 3b/c. Basically, it DOES dry and straighten pretty well, but i've also been getting alot of split ends, and my hair is definitely dryer. Therefore, you should only go for it if you're willing to condition it a bit more then usual.
