I would constitute my hair as a 3c and I got the Coppola treatment two weeks ago. The difference is amazing. I let it airdry and it will not be stick straight. There was some wave so it looked quite nice. You can blow dry it stick straight or if you want some curl/definition you can blow dry with a round brush. I love my straight hair now and will definitely do it again. I can send you a picture of the hair if you'd like to see.
