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 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.

Awesome!

First off, the sample of this and the conditioner were HUGE! That alone sold me. I really liked how it left my hair feeling. I have pretty shiny, slick hair so any kind of bounce after washing is nice.

Better than the shampoo
Sampled

I enjoyed this product. I dont use a lot of conditioner since I have thin hair, but this goes on light and won't weigh me down. It makes my hair soft/smooth without leaving it greasy.

I read about kerastase in a magazine and how well it worked so decided to give it a try despite its price. I works ok but for the price I felt it could have done more. I didn't fell that it was worth it. purchased shampoo and conditioner

A great product but still need more
Sampled

I have fine dry hair. While this product was fantastic it didn't dramatically change my hair in just one or two uses. I would still take the chance on the full size because I am confident in the results of the samples that with continued use I would reap the benefits.
