Stars (of the celestial variety, though the same could be said for Hollywood) lose their allure when their brilliance fades. Which is exactly the case with color-treated hair: Fading means dull, damaged, lifeless locks. This sulfate-free shampoo maintains your hair's brilliance, preserving color depth for up to 40 days. Shine on.
I was so psyched to get this in my Birchbox this month! Such a nice big sample size too!! I had previously gotten a sample of the age reversing shampoo from Birchbox and it was just one of those little packets like you get in the newspaper or whatever. This stuff, like everything from Kerastasse, is wonderful. I think I prefer the age reversing one simply because it is more moisturizing and at the moment that's what I need more than color retention but I have been planning to go redder soon and I will definitely pick up a bottle of this when/if I do since red fades so quickly.
