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.

Helps with fine hair
Sampled

I've used all sorts of protectants to try and keep my fine hair from splitting or frizzing after blowdrying; This product has done a great job of keeping my hair healthy despite daily heat use! I'm very happy with how soft my hair feels and smells (very light and fresh baby-powder like smell) when I use it!

Huh?

I have curly hair but can also blow it out straight...I feel like other products I have received through Birchbox have been more hydrating than this particular product...

Gave it away

I have very curly hair and very seldom stray from my normal products. I also air dry my hair daily. So this product wasn't effective or necessary for me.

Soft hair

I have a lot of leave in conditioners. Honestly I didn't notice to much of a difference between this and most drug store brands.

Softest hair ever
Sampled

I have quite long, thick hair but even just 3 or 4 sprays of this works wonders! It detangles and makes combing my hair after washing much faster and easier. It also leaves my hair extremely soft and moisturized, whether I blow it out or leave it to air dry. Using this almost guarantees that I'll have a good hair day!
