Number 4 Hair Care

Birchbox Breakdown

This singular shampoo takes inspiration from both Paris and Texas. Yes, you read that right. The gorgeous packaging and fresh scent are a nod to French style, while the scientific formula is designed to turn fine, meek strands into big, bodacious hair. You’re on your way to full, voluptuous strands.

How it Works

This sulfate-free formula is designed to detangle and cleanse hair without weighing it down. It uses natural lemongrass, golden seal, and gooseberry, plus the brand’s four signature Liquid Complexes™. Each complex is a different blend of natural ingredients designed to help protect, purify, strengthen, and revitalize hair.

Not too harsh

I am always afraid to try shampoos because of my thin hair and harshness of chemicals. My hair really seemed to show body after styling when i used this,

Eh, was ok

My hair is very thick already so don't need the extra volume. Will stick to my shampoo. But it smelled nice.

Too much scent

It is a nice enough shampoo, but the perfumed scent was just too much and lingered too long for my tastes.

Love this shampoo!

Smells great and works pretty well! I already have a lot of shampoos to go through right now but I might purchase this in the future.

Nice Shampoo

I was happy to have this sample in my birchbox, and took it on a trip. It smelled nice and got my hair clean. I have thick, wavy hair, so I'm not sure that I needed to add any volume to it, so I'll stick with what I'm using for now.

Perfect!

This shampoo is wonderful! My hair is fine and I usually struggle to get volume in it, but this shampoo does the trick. It also makes my hair super soft to where I don't need to use conditioner. Even better, a little bit of this shampoo goes a long way, so it lasts for a while. Love it!

My hair is so soft!

This shampoo is fantastic. It smells great, and is very subtle. I love the lather you get from it. I think it really does a lot for my very fine hair, volumizing shampoos rarely do anything! But this one really does. A little bit goes a very long way as other reviewers said. I only wish I could say the same about the conditioner that I sampled as well.

Really Nice Scent

I really enjoyed this scent and the clean feeling I got from the shampoo. It lathers up really well and it doesn't feel like I get a build up from the shampoo. The best part really is the scent though.

exactly what it claims to be

my hair is very fine and very long, so volume is like a pipe dream to me, but this shampoo delivered in lots of ways. the smell is very sweet and subtle. the whole shower experience was just lush. and while, I didn't get dolly parton volume, I definitely noticed a good amount of lift.
