Review (4/5): Used it twice. My go 2 product
I've used this product twice. I had my friend do it for me in Miami while on vacation and it works! I have wavy frizzy hair and live in NJ. Summers can get pretty humid. The product lasted about 3 months. Once I was finished with the shampoo and conditioner it came with I used a keratin shampoo. (Use a sulfate free shampoo/conditioner).
My first application I left 24 hours and the second time I used it about 40. I had great results both times. the product has a slight odor when applying but nothing as terrible as some reviwers described. I would definetly recommend the product.
