Very poor quality. Products for supermarkets only do the job, even though the supermarket's own brand is better than this one.
Also, it is not sulfate-free, which is the worst enemy for straightening treatments, so it is not suitable for maintaining after keratin.
My hair became duller and more unruly, even though it was healthy before.
Complete disappointment

Their smell is like a cookie, it enchants you. Very gentle shampoo, doesn't create much foam due to the lack of SLS, which is good because it means it is more natural and doesn't affect the keratin treatment you have done, leaves the hair soft and incredibly scented, the mask is thick, buttery, with the same amazing smell, very nourishing and leaves the hair silky. The conditioner didn't impress me much. It's like I didn't put anything. The kit is definitely worth it for those who have had a keratin treatment, it saves the hair and prolongs the result of the treatment. I will buy it again!
