Birchbox Breakdown

This decadent conditioner helps to bring dry, over- styled hair back to life. It’s loaded with moisturizing natural ingredients that calm frizz and restore fried ends and it also protects from future damage. Don’t tell our hair stylist, but this product is the reason we can go so long in between trims!

How it Works

This rich formula helps to rebuild hair inside and out: vitamin B5 and jojoba help to nourish and hydrate dry strands, while Number 4’s™ proprietary Liquid Complexes™ use potent natural ingredients like acai berry, vitamin C, and black current to moisturize, protect, and strengthen hair.

How to Use

Use on clean, damp hair. Depending on hair length and thickness, work one or two pumps through the ends and mid-length of strands. Rinse completely and style as usual.

Great Conditioner

I bot this conditioner because I bot the clarifying shampoo and I like this just as much as the shampoo. Makes my hair shiny, manageable and has a nice fragrance!

awesome conditioner!!!

I keep coming back to this one, even though it is a bit pricey, and i'm not Rockerfeller. it's lght enough so it doesn't weigh my fine hair down, yet moisturizes so i have no frizz, it's smooth and shiny. the smell is springy, a little flowery but not too strong.

Super rich conditioner that smells sooooo good!

The Number 4 products are my new obsession. The hydrating conditioner really makes my much abused color treated and heat styled hair look shiny and healthy. And the smell is absolutely divine - imagine a musky honey scent. Yeah, it's pricy, but it's worth it!

Love it

I've been using this and the shampoo for about 4 months on medium fine, home colored hair. It has made my hair super soft and fluffy but it doesn't give the 'slip' factor of a more cone heavy product so I use a detangler or oil as well. The balance of protein and moisture has been perfect for my hair. It has never been so voluminous or easy to style! The smell is strong and gorgeous, complex and heady. Without giving me a headache or conflicting with my other products. Honestly I would buy this as a perfume. In those 4 months I've only used 1/3 of the bottle since the measured pump helps you ration it, it is concentrated so you really don't need a whole lot, much less than anything else I've tried. In short, I'll be re-buying.
