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.

Awesome product!

I was scared to use this because I didn't want my hair to get greasy or weighed down but it was amazing. My hair was super easy to comb out and didn't seem like any product residue was left in my hair when it was dry.

Transformed my hair
SampledPurchased

This is hands down the best thing that has ever happened to my hair. I have very thick and coarse hair. When it gets wet it tangles. Combs and brushes often break my hair or break in my hair. I have searched my entire life for the holy Grail of detanglers and this is it. I spray it on my hair as soon as I get out of the shower and BAM! No more tangles! My hear is the healthiest it has ever been!
