Birchbox Breakdown

As self-confessed blow dryer addicts, we put our hair through a lot of stress. To keep our strands from a styling-induced meltdown, we'’ve been using this extra hydrating leave-in conditioning mist. It doesn’'t just protect hair from heat damage; it also doubles as a color protector and UV shield. The sulfate-free formula sinks in quickly and has a pretty floral scent thanks to white freesia, amber, and musk. Natural conditioners——including black currant, soy yogurt, algae, and yerba mate——combine to restore hydration to dry hair, while the unique UV/Color Polar Shield protects dyed or sun-exposed locks. Soy and vegetable proteins repair damage caused by heat and chemical styling. And don’'t forget about the defrizzing factor——anti-static technology tames flyaways, making hair more manageable and easy to style.

How to Use

After shampooing, wring excess moisture from hair and towel dry. Holding the spray bottle upright, spritz product evenly. Using a wide-toothed comb or your fingers, gently work the product through hair from root to tip. Style as usual.

Great fragrance!

Really enjoyed the smell. Got in my sample box, not really relevant to me because I don't blow dry my hair.

Great for colored hair

Just spent a small fortune on a cut, color and hi lights so finding this in my box was perfect. It helps with tangles but more importantly it helps protect your color in the summer sun.

I liked this product although I didn't really love the smell for some reason. But it did help my frizz calm down a bit.

I have naturally straight, easy to manage hair but it is down to my butt long. This product is great to help quickly brush out any tangles.
