  • excellent product
Incredible and long-lasting results! I bought this kit for the second time and I couldn't be more satisfied. From the first use, I noticed my hair was softer, shinier, and frizz-free. The shampoo and conditioner cleanse and nourish without drying it out, and the mask is wonderful: it leaves my hair silky and manageable. Plus, the best part is that it's salt- and sulfate-free, which is perfect for maintaining my straightening for much longer. 100% recommended! It's ideal for those who have undergone a keratin straightening treatment and want to maintain the results for weeks. I will definitely continue to buy it. ... show more
