I had the treatment done two weeks ago, and my hair looks great!! It only takes 12 minutes to dry and I have long hair down to my waist. I always use the shampoo that the stylist gave me, because I want this straight hair to last as long as possible! I also bought the conditioner that goes with the shampoo, so my hair will stay healthy and shiny! Even in the worst humidity, I have pin straight hair!! When this treatment wears out in 3 months, I am going to be depressed, will have to get it done again. This is the best beauty treatment I have ever had in my life!!
