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.

It smells so great!!! It made my hair soft almost instantly. I've used it on my niece as a detangler and it works wonders. I will be ordering the full size. My hair was shiny and light weight. Great product.

This was perfect for my hair type (very thick and wavy) and kept my hair from feeling gross when applied after swimming. I found it to work really well as a detangler and the smell is amazing!! I will be purchasing the full size bottle :)

This product smelled great. Admittedly, I am a blow dryer and flat iron admit. This heat protectant was great. I was very pleased with the amount dispensed per spritz & the quality of the product.

I always love trying new hair products and Number 4 never fails. It lives up to what it says it will do and it smells great, which is always a plus.

I think this is good, but it can be hard to tell with styling products after only one use. My hair was shiny and silky after using this, so I think it's doing something. I will continue to use and see if I see bigger results
