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.

Makes my hair so soft

I love this spray. I've gone through 2 bottles already, it's perfect. I get out of the shower, spray my hair down, comb through and let it air dry and it is SO soft and smells amazing. This whole line is awesome but this spray is a beauty MUST

Fantastic for straight hair

I have straight hair that is very long. I love this product because it detangles without weighing down your hair.

Love it!

I love this stuff! I got a sample of it in one of my BirchBoxes and it's wonderful. I blow dry my hair a lot, and I have thick curly hair that needs heat protection. This stuff keeps my hair shiny and helps reduce the heat damage. I know some people complain about the smell, it is a bit strong when you first spritz it in, but once you blow dry it the smell is not strong. Great product!

Not my fav, but it does the job well

When I received the product, it wasn't what I expected. I expected it to me more creamy/goopy. I was hoping for this texture because my hair is very fine and is dried out/damaged easily. Instead it is a very light mist. Now that I have used it regularly, i can do without the creamy texture. My hair feels healthier and stronger. I do feel like I have to spray A LOT on my hair to get the full benefits though. The fragrance is really nice.

Love the smell!

First off, I love the smell of this product! Second, it works wonders for me as a detangler. My hair is super easy to tangle and combing after a shower can be difficult. This is better than any detangler I've ever bought in a store. Plus it protects! What more could you want?

Love it!

No. 4 Super Comb Prep & Protect has to be one of the best leave-in conditioners out there. It's not heavy but yet it gets the job done. It also has a wonderful smell. Some have asked what fragrance I was wearing.

New Favorite

not sure I can live without this. It is so light and is one of the only things that lets me comb through my hair. It does not way hair down AT ALL. Perfection!

good product

I think I left my hair very soft and ready to style
hair is shiny and silky.
the only thing I did not like is that it ends too fast

Must have!

If the smell alone doesn't make you buy it, the smile on your face after use will! This product brought my damaged blonde hair back to life. Well worth the price.
