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. 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 Smell!

I've been putting off finding a hair heat protecting product, so this arrive at the right time. I don't think a sample is sufficient to see results in how healthy my hair is over consistent blow-outs or hot flat irons, but assuming the product is doing it's job, this one smells great on top of it! Not too strong, just very fresh. I get a whiff occasionally throughout the day and just love it!

Silky smooth!

Smells sooo good and makes my hair feel nice and silky. However, I'm not a fan of leave-in conditioners in general, so I probably won't be purchasing this anytime soon. I did enjoy the sample and didn't find anything wrong with it! I just don't use leave-ins...

Meh...

I love that this product provides uv protection however I can't get past the smell. Overall it seems to do it's job but I probably won't purchase a full size bottle.

Smooth

This hair treatment is great for after showering and using before blow drying. I have thin hair and it tends to damage easily with my daily hair dryer and flat iron use. When I used this, I was able to skip the flat iron on some days depending on the humidity.

Frizzy hair

I have a lot of thin, soft, manageable curls on the lower half of my hair, but on top I have thick, coarse, tight waves that frizz when blow dried. Unfortunately this product has not solved my hair issues. But it smells great and doesn't make my frizz feel like straw.
