I was impressed with the quality of this conditioner. I wish we had gotten larger samples! These would make great additions to the box.

Keratase is great for soft & shiny hair
Sampled

I received this as a sample in Mays Birchbox and I love it. My hair looks so shiny and healthy. It feels so soft to touch and smells so nice. This is one of the best conditioners I have ever used and I am very pleased with the results, my hair looks so much more healthy than before.

smells wonderful, makes hair soft. Way to expensive for me to purchase.

It's Shampoo...
Sampled

I used the sample size of this from the May Birchbox but really the little foil package was hardly enough product for my long hair. I'm not sure I can honestly comment on it's effectiveness.

LOVE LOVE LOVE this product. Made my hair smell so good. Normally I have the way my hair smells, even with good smelling products, but this stuff had me smelling my hair all day! This conditioner also didn't give me static, which is very hard to find for me personally. My hair felt very light and clean and I love this product!

After a single use I think that I like this conditioner, but am not willing to risk purchasing it without a larger sample size. I will get a few more uses out of the packet, but I feel like I need to be able to use a hair conditioner for at least a week to notice any true difference, especially since I already use a high quality conditioner.

Kerastase Lait Crystal

Of all the Kerastase products in this month's Birchbox, this was the one that topped them all. I've never had such silky hair after using a conditioner. Next time I get some extra cash, this might be a splurge I indulge in.

Moderately Good for Long Wavy Hair
Sampled

I liked the conditioner more than the shampoo, but less than the Lumiere Liquid. This conditioner didn't leave my hair feeling any better than my normal one, but I do think I gave me a good punch of volume, though it didn't help with my wavy hair frizz.

Decent product, but I dislike the "packet" sample. I would rather have a bottle.
