Number 4 Hair Care

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.

How it Works

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.

Worked as designed

Worked great on the ends of my hair. A day or two after using it I noticed a difference in the tangles in my hair.

I received this as a sample - and it's probably my favorite so far. My thick, long hair dries soft-to-the-touch and wavy without needing any other curling or frizz-preventing products.

Great for dry hair

My is ombre, so my ends tend to look really dry, and brittle sometimes. This product is great for protecting and hydrating, without making my hair heavy or weighted down. It's one of my new favorite hair products

Love, love, love

I purchased a full bottle after using this product a few times. My fine hair isn't a fan of the Texas weather -- or any weather, really. This gives me a smooth look without it being weighed down. It smells really nice, too.

Great for tangles!
Sampled

My hair always gets super tangly and I was excited when I got this sample-- it worked for me! I don't really blow dry or straighten my hair very often, so this sample should last me a while.
