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.

Great for medium length hair too!
Sampled

This shampoo and conditioner worked great on my hair, which is medium length, but very thick. It had a lot of bounce and smelled great.

Too heavy for fine hair
Sampled

I'm still to find a good conditioner for long, straight, fine hair. This conditioner helps with detangling hair, but unfortunately it is rather heavy and weighs my hair down quite a bit. Instead of using conditioner, I have now resorted to oiling my hair with cold-pressed almond oil at night and shampooing it out the next day once a week. This has been working pretty well and has really stymied hair fall, and I'm still to find a conditioner that does a better job.

Left hair very greasy
Sampled

This left my hair very greasy and oily after only the first day using it. I used up the entire sample on multiple washings just to be sure. Not good for my hair type.

Too expensive
Sampled

Just like the companion shampoo, I really like how this made my hair look and feel. However it is way out of my price range. If you have the money, go for it!

Let me say, no no no no...no.

Left my hair un-moisturized, dry...hated this. I needed something with more weight to it to keep my hair detangled and shiney. I stuck with my supermarket brand that works a million times better. Will not venture out to Kerastase products again!

Awesome

I love the way that this makes my hair feel! I feels so soft and luxurious, as if I were a hair model, flipping my hair back and forth.

Not Impressed
Sampled

I didn't use the shampoo with this product, but I tried the conditioner because the ingredients seemed ok. I was not impressed with the look of my hair after using this product. My curls were not as moisturized as they are with my regular conditioner. It simply wasn't for me.

It's Okay

Great, lightweight detangler. A little goes a long way, which is nice considering the price tag on this stuff. Smells great, too!

Conditioner is extremely important for my hair and Kerastase is the best of the best - so why not pamper my hair a bit with this amazing product.

The Best

My absolute favorite brand of hair products. Only complaint was sample size was way too small. I hadn't tried this type before so that was nice.
