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.

My go-to product for daily use!

I'm not very high maintenance with my hair, but I've started using Prep+Protect every day. It helps to maintain my hair's strength and volume before blowdrying and makes it a lot more manageable on days when I don't blowdry. I've been seeing a lot fewer tangles in my hair since I began to use Prep+Protect. I've even gotten my boyfriend used to it and he'll reach for the bottle as a reflex after showering.

Number 4 does it again

I love number 4 products anyway but this is even better! I love it and it makes my hair feel so good! I will definitely be buying this once my gigantic sample runs out!

Obsessed

I have fallen in love with every no 4 product I've tried and this is no different. This is the best product to detangler hair and prep for a blowdry.

great

Smells great & makes my hair silky smooth. I don't have color treated hair so I'm not sure the effectiveness of color protection.

This stuff is fab!

I love this product! It smoothes, softens, and detangles, and it smells really good. One of my new favorite hair products.

I like the way this protector feels in my hair. I like to use it before I curl or straighten my hair.

Love

Great new product in my hair arsenal! I've been loving the Number 4 samples and this is no exception. I used this with the shampoo and conditioner I had gotten in a previous Birchbox and I love the texture of my hair after using it! Great smell that lasts throughout the day. AND no more sore head trying to comb through the tangles!

Conditions

This is a pleasant-smelling product. It did weigh my hair down a bit and did not really control any frizz. It did condition my hair but overall was too heavy.

This spray is officially one of my favorite Birchbox products I've ever received! Living in obnoxiously humid Florida, this spray tamed my flyaways and kept my hair so soft, without feeling greasy like other hair oils.
