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

Get this conditioner for free when you spend $30+ on any full-size product(s) in the Birchbox Shop. Just use code KERASTASECONDITION at checkout. Limit one per cart. Cannot be combined with other offers. In order to return any item in your order, you must also return the conditioner.

How to Use

After shampooing, squeeze excess water out of hair, and work a quarter-sized amount through your lengths and ends. Leave in for up to three minutes, and rinse away with warm water. Stash this travel-size bottle in your carry-on or gym bag for sleek strands even when you're on the go.
