Not to scare you but please make sure the person knows what they are doing!!!  I had a body wave put in my hair about 3 years ago (by a professional) and you could not believe what it did!!!  My hair was a frizzy mess ...no curls just frizz!!!!  The hair dresser felt horrible and she kept having me come back ....she was trying different things to make it relax.....nothing worked!!!   
My hair had color on it at the time of the Body Wave and that is why they think it frizzed. 
I hope you have better luck than I did!!!
