This is a gimmick

I bought the entire line: shampoo, mask, detangle spray and this overnight serum and what I noticed most is how badly it dried my hair out. I tried them all individually and together to see if it was one item or all of them but no matter what combo, if one of these products was in rotation, my hair was straw. For reference, I have medium thick, mostly straight, partially bleached hair. I have other Kerastase products that I love but this entire line wasn't it

A noticeable difference in my hair

I absolutely love this serum. I apply it before bed, and by morning my hair feels noticeably softer, smoother and more manageable without feeling heavy or greasy. My hair is fine, color-treated and naturally wavy, so finding something nourishing that doesn’t weigh it down can be difficult. Since adding this to my routine, my hair has felt healthier than it has in years, and I’ve noticed significantly less dryness and breakage at the ends. I’m almost finished with my bottle, and this is one product I will definitely repurchase. It truly feels like overnight skincare for my hair!
