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.

Great leave-in!
Purchased

I love this leaving conditioner so much! It makes your hair soft, silky, and smooth. It's a little pricey, but it is worth the money. Highly recommended for a daily leave in conditioner.

Daily Use
Purchased

I heat style my hair every morning and since I received this product in my monthly box I have used it almost every day. I purchased the full size product and I have been very happy with it. Once I straighten my hair I can really tell how much it helps.

LOVELOVELOVE

This is such a great product. I spray it on my hair after a light towel dry post shower.. silks my hair.. absolutely NO tangles after this product. SMELLS PHENOMENAL. Also, I occasionally spritz it on my dry hair for a mid day/night freshen up. The spritz from the bottle covers a lot of ground, and I actually like when it gets on my face/skin (is that weird? :) Would recommend this to everyone.

Great product! Works wonders!

I loved this sample so much, I'm ordering the full sized bottle. It works great at detangling hair, and it smells amazing! Worth a try!

Good for fine hair

I love this spray. I have long fine hair. It didn't weight it down. Has nice neutral smell and after consistent use you can definitely feel that it protects your hair.

Great leave-in conditioner

This is one of the first samples I received and bought it immediately from Birchbox. I used my sample to travel with and bought a full size for my house. Great before using hot elements on the hair.

not sure that it's worth the price

It's a good product. I have used many others that do the same thing but smell better and are a more reasonable price.
