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.

It is not as strong
Purchased

This conditioner is not that good for people with long thick hair. It does not detangle and when I put it on I feel it is quickly absorbed by the hair without doing anything noticeable to it. I purchased the mask and it feels more like a conditioner than this.

Love the Results
Purchased

Kerastase conditioner is amazing. It leaves my hair feeling so soft and smooth. You don't need to use too much of this product to see results. It is expensive for conditioner, but the results are worth it. This product is great for long fine/normal hair.

This conditioner smells great and actually does give my hair a noticeable lift. I have super fine and straight hair and since I've started using this, I get a lot more volume and fullness after styling. Highly recommend even though it's pricey.

Smells wonderful

Love love love this product! I've always loved Kerastase - this is my first experience with this particular product but I loved that they made one specifically for thick hair. I have incredibly thick hair & this seemed to work great for me. Plus it smells fabulous! I definitely recommend this to anyone else with thick hair! I loved the shampoo as well - & I don't need to use a large amount of the conditioner! Thankfully it seems like it will last a bit longer!

works well on fine hair

I was really happy that this product did not weigh my fine, color treated hair down, like so many conditioners tend to do. It also smells very nice. However, did not quite hold up against kerastatse's lait it vital conditioner. Was pleased overall.

I'm a fan!

I love this Kerastase line for long hair! It's so hard for me to find good products without silicone that are made to care for long hair but this shampoo and conditioner make my hair so flowy and light -- a major feat for my hair! Definitely give it a try!

Great conditioner for long hair

I use this product with the shampoo for my fine color treated hair. It makes my hair soft and silky. I will be switching to a richer conditioner in the winter however as this conditioner is on the lighter side.

Kerastase Can Do Better

Like my review for the shampoo version of this product...it works fine, but isn't as luxe to me as the brand's Bain Satin line.

Does this conditioner work? Yes, but for the price, and average kind of scent, I'd rather spend it on something with a bit more "oomph"!
