Cristalliste Lumiere Liquide Luminous Perfecting Essence By Kerastase - 1.7 Oz Serum

[This review was collected as part of a promotion.] This is a great product. I use it before I blow dry and flat iron. I also use just a tiny dab when I need a little added shine. I am biracial and I have naturally curly hair. My hair is also frizzy and unruly at times. I have been searching for products my whole life that work well with my hair and I finally found it. This bottle lasts quite awhile, I have long hair but all I ever need is a little . I'll never buy another product.

I started using this about a year ago. I have very long, naturally straight medium brown hair. I wash my hair every 3 days. I switched over to Elixir Ultime about a month ago, but I have about a quarter of a bottle still left of this product. I'd be willing to bet it would have lasted at least a year. I used a full pump every time and used it religiously. It made my hair look shiny and feel silky without ever looking heavy or greasy. I love it!
