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.

its okay

It works perfectly, and detangles my hair, my hair has a lot of tangles after washing it. I use a similar product that's why I won't be purchasing. I hate the smell of this one though, only downfall

makes my curly hair soft and shiny

I love this product. I like the mist spray, and the product smells great. It makes my hair extra soft and shiny, which isn't always easy with curly hair.

Not in the budget this month (plus I still have some left from the generous sample!) but hopefully another month. Works great

Its ok!

This product worked just fine, but I can't say it helped my hair any more than any other similar product that I have used. But the price is not good!

average detangler

I was mainly looking for a detangler and this product was average compared to similar products on the market. I had to use a lot to get the desired outcome.

It actually works

I have curly hair so I can't attest to having combed through my hair, but it still felt conditioned after I used this. It kept the frizz down all day too, and since it's super light, it was really nice all day.
