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.

I dont like this brand, but i like this product

I have gotten samples before from this brand that I didn't like. This doesn't smell great but I actually really like it, doesn't weigh down my hair or feel greasy.

It was okay

It was just okay. Didn't really do much for me. I don't normally blow-dry my hair. I still had tangles, frizzes, and it kinda smelled weird.

Helps drying time

It takes me forever to dry my hair. Usually 10-15 minutes. This product has help cut a few minutes off the time. I'm not sure if it is in the budget this month but it was a nice surprise.

Nice de-tangler!

I liked this product! Nice size to take traveling as well, when you never know what the hard/soft water will do to your (color-treated) hair. Would buy when I run out!

Good Detangler

Goes on easy, makes brushing through hair effortless. Not heavy, very light and does not weigh your hair down.
