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 love this leave in conditioning mist. I love that it protects my hair from heat damage. I use it every morning and it smells so good.

Weird spray, awful scent
Sampled

This purports to act like a detangler/leave-in conditioner but the spray was so unfocused I was scared to use enough to even give it a good test. Plus the smell is really revolting.

Great product

I had tried similar products before, and while the may smell better, this one does a fantastic job of providing the detangling/conditioning I need on my straight, fine fair.

Just not for me
Sampled

This product just didn't work for me. I will probably give it to my daughter who has a very thick hair and see if it works for her. It did smell very nice.

Definitely does the job!
Sampled

Just the right amount of extra moisture for my fine, dry ends. Hair was silky & shiny all day. Maybe almost too soft? Haven't tried but it would probably slip right out of a ponytail.

Purchased it

It's great, smells good and I really feel it's good for your hair. I swim everyday and blow dry my hair so it needs some TLC. I spray it on damp hair before blow outs and it shines and smells nice. The full size format is a little pricey but will last a long time, probably a year...

Cool but...

Cool product, very necessary if you blow dry or style your hair with heat often. I don't so it was a little unnecessary for me.

loved it

love love loved this product! I usually let my hair air dry and this conditioning spray made it so much more manageable and soft, and I've gotten multiple compliments. Probably going to purchase the actual full size product in the future and would definitely recommend it to others with thick hard to manage hair like myself.
