It offers hydration and reconstruction. It has a perfect scent and restores hair damaged by bleach. It doesn't perform miracles (what's broken is broken) but it keeps the hair in good shape and fills the hair shaft. I'm buying it for the second time along with the spray and the mask. I have fine hair that I lightened with bleach (again). I got a white result but unfortunately the ends and lengths got burned and split, though they didn't become elastic... Those who know, know. The first time I used the series I saw very good results. Now that I made the same mistake again, it saved me once more!
