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.

Love it!!

Tried this product on the ends of my my dry hair and it made it feel smooth, looked a little shiny and smells great! Works better than most products I have now and I can't wait to buy it!

Did nothing for me

Didn't like it. Didn't help detangle, didn't help with frizz and I disliked the smell. Save your hair, time, and money with Beauty Protector

detangles, conditions and moisturizes

Since I rarely use heat on my hair I will focus on the other attributes of this product. It did a great job of detangling my hair while conditioning and moisturizing. I have very thick, long hair, so I needed a lot of product to get the desired results.

Frizz Free

This works great with my frizziness! I'm definitely buying this in full size.

Works well
Sampled

This doesn't smell the best but it makes my hair very soft. I wish it tamed frizz but at least it detangles my hair well. I may consider buying a full size since it will make it easier to comb out my hair. As my hair gets longer it gets worse even though it's straight.

Leave in Conditioner

The only bad thing about this product is the smell. It has an odd smell to it. Other than that, it is a great product. It keeps my hair hydrated. The best part was that it did not make my hair greasy at all, which I was worried about. It did not make my hair frizz free, but it was a lot less frizzy than normal.

No Noticeable Effect

I sprayed a ton of this in my hair but did not notice anything different. Will give it a few more tries, but so far is very expensive for no effect.

Great!

It came just in time for a trip to the beach. I loved that my hair was protected and it really did feel smooth.
