I was a skeptic, and now I believe! I had "permanent straightening" done in high school (about 12 years ago) and it did not work, at all. So I was hesitant to try again and spend the money. Anna and Paul guaranteed me that it would work, and it did! I am so pleased! I have very coarse, frizzy and poufy hair. I washed it for the first time today, did a quick blow dry, and was out the door! Thank you Paul for doing it for me, and thank you Anna for your patience when I was a nervous nelly! I read every review there was and did a lot of research before I came here. I am glad I did and their 5 star reputation is for a reason. If you are thinking about getting it done...do it!
