Number 4™ Super Comb Prep & Protect

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.

Great surprise

Didn't expect this in my box for I was to be getting another hair product but so glad I got this instead. I have very dull flat hair and this product made my hair look and feel healthier.

I really enjoyed this sample.

It has a slight smell and it works to detangle my hair just by running my fingers through it. My hair is thin, brittle, but super greasy normally with leave in conditioners. This product is light and airy. I really like it.

Best Leave-In Conditioner I've ever tried

As a lifeguard, a good leave-in conditioner is essential. Between the sun and chlorine, by the end of the season my hair is ruined. Leave-in conditioners definitely help me to save my hair to a degree. And then this little bottle came along in my birchbox and my hair is saved! It leaves my hair feeling soft and full and healthy. I just spray it in my hair before I comb it and again after and I can then style it or let it air dry and my hair feels amazing for the rest of the day!

Hair-nectar of the Gods

I had zero clue of what to expect, when this arrived in my Birchbox package...and it surpassed all of my expectations. It smells delicious and makes my hair silky-smooth after each blowout! I can't be more thrilled with it.

Just OK

It's okay, nothing special. I have used the No 4 hairspray that was in my Birchbox a couple of months ago and loved it. I was expecting to love this too, but it's just OK.

amazing!

this product smells amazing. It comes in a decent size. You can probably use it four times. It makes my hair soft. Did I mention it smells great? I would be purchasing the full size bottle. I can't wait to pass on the good word about this product.

not great, nor bad

I personally haven't noticed a difference in my hair after using this product. I have thick, and naturally wavy hair. Maybe this will work better on someone with a different hair type, just not for me. I also didn't care for the scent.

Great spray

This spray was clean and felt great in my hair. I recommend products that treat color treated hair with care. It didn't build up on my scalp and was light.

Easy to Use, Effective, Wonderful for Fine Hair

I have very fine hair so I am always skeptical of using any leave in conditioners as they tend to weigh down my hair and prevent any volume. This product was lightweight, has a nice scent, easy to use in air-drying hair and added a lot of shine and softness to my hair that lasted between washes.

Worth a try

I used it on my damp hair and it did what it claimed to do. It made it way easier to brush through my messy, thick, dry hair. So, overall, I would recommend.
