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!

Good Product

I like the product, but as I already buy salon quality shampoo and conditioner, I don't have a need for a 2nd conditioner. If you have found your hair in need of a good conditioner and don't want to deal with the hassle of leaving a conditioner in for 5-10 minutes before rinsing in the shower, then try this spray.

Decent product

It's a fine quality leave in conditioner and detangler. Nice and lightweight, and doesn't leave my air feeling limp or greasy like some products have. Doesn't seem to offer much in the way of heat protection though, and doesn't have any real scent to it. For similar products, I much prefer the Beauty Protector spray (also available on Birchbox!).

Soft, not greasy hair!

I just sprayed this on the ends of my hair, as my ends are always so dry and my roots get greasy easily. It didn't make my hair feel greasy, just soft. No longer course and straw-like.

Nice

I had never heard of the brand before, but I tried it on my daughter (who has very silky, straight hair) and myself (very course, curly hair) and it did a great job of detangling without weighing the hair down. Smells awesome, too!

Loved the smell

Number 4 Super Comb Prep and Protect was very light and smelled wonderful. My hair is very thin and fragile so a product that can detangle but is lightweight is important to me. The aroma was an added bonus.

Super smooth hair, less frizz!

Smells good and makes my naturally wavy and frizz-tastic hair MUCH less frizzy. It air dried super nicely and the ends even feel good. Love this!
