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.

Pretty good

A decent hair protector, I just have another brand that I love so it's hard to compare.

Not my favorite
Sampled

Not a huge fan of the fragrance but that's just person preference. I feel like it makes it harder to comb through my hair once I spray it and once dry my hair feels a little weighed down.

Lightweight but effective.

I have very oily hair and product seems to easily build up so I am always leery of putting extra stuff in my hair. This was not heavy at all. Doesn't take much to do a good job.
