Post-shower, enhance your shine by smoothing Kérastase’s Cristalliste Lumiere Liquide through damp or dry hair.

Kérastase

Birchbox Breakdown

The hair-centric among us have one burning question for Blake Lively: how does she get those gorgeous waves? Though our curiosity may never be fully satisfied, we can all get better hair with this shine-enhancing conditioner, which was inspired by the “Gossip Girl” star. Specially designed for long hair, it detangles knots, repairs damage, and glossifies each strand. Next up: show-stealing locks worthy of a red carpet premiere.

How it Works

Whether you have a thick mane or long, fine locks, this unique conditioner will give you tremendous volume and softness. The secret lies in the triple-threat formula. Liquid light reflectors deliver mega-watt shine, while eco-friendly polymers restore brittle, uneven follicles on a microscopic level. Vitamin-rich aloe vera hydrates hair without weighing it down, giving you the silky texture you crave.

How to Use

After shampooing, squeeze excess water out of hair, and work a quarter-size amount through your lengths and ends. Leave in for up to three minutes, and rinse away with warm water.

a hairstylist who blew out my hair once recommended i try the cristal line from kerastase. this was the last conditioner/shampoo I purchased before deciding to go more natural/organic with my hair products. that should give an indication of how satisfied I was with it. I bought this as well as the shampoo that matches it and i have to say - this brand is overpriced and overhyped. And I did not like the amount of silicones and synthetics in the list of ingredients. it wasn't horrible to use, just not in line with the kind of products I want to put on my head anymore. also... the amount of product for the price is kinda cray. shouts to birchbox for always having the best promos that make buying expensive stuff more fun and feel worth it.

Worth the splurge
Purchased

I have bought the shampoo and conditioner over and over - Kerastase really does offer amazing products and worth the price. The conditioner is surprisingly very moisturizing for how light it is. Perfect for my long, fine hair.

So overpriced for the quality
Sampled

This is very much something that you would buy at a drugstore. I am just not seeing this as a high-end product. So much alcohol in the ingredient list, which is what dries hair out!

Just okay
Purchased

I have long wavy hair and after reading the blurb I thought this could be the perfect conditioner for me. I did not feel like this conditioner gave my hair the moisture it needed or detangled my hair after I was done washing it.

I love conditioner that actually deeply moisurizes
Sampled

I need extensive detangling, as my hair somehow tangles itself every single day, and I tend to have rather dull looking hair. It is awesome when a conditioner can kind of handle a few issues at once like this one does.

Simply put, there's a reason why Kerastase products are so darn expensive: they're top-of-the-line. Just like the other Kerastase products I've tried, this smells amazing and does what it says it does.

good conditioner
Sampled

This is a really high quality conditioner! It made my hair feel really thick and shiny and smooth and it smells pretty good too. Keratase is a really great brand and you can't go wrong with any of their products.

Meh at best
Purchased

For the $, I expected something amazing. It's good but something less expensive works just as good. Doesn't detAngle or prevent frizz.
