Birchbox Breakdown

This shampoo and conditioner duo 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 formulas are designed to turn fine, meek strands into big, bodacious hair.

How to Use

Dispense shampoo into hands, work into a lather, and massage into wet hair. After rinsing and wringing out excess water, apply one to two pumps of conditioner to hair, concentrating on mid-shaft and ends. Rinse away.

Best Shampoo/Conditioner I've Ever Tried
Purchased

I am bit of a collector of good shampoos and this product is by far my favorite. It gives my hair great volume, without making it feel heavy or oily. I can't rave about this duo enough!

Not my favorite
Purchased

My hair is fine, and on the thinner side so I was hopeful for this product. I have tried other No.4 shampoo's in the past, and loved them! This one seemed too heavy for my hair, and weighed it down. I used one pump of the shampoo, and made a point to only condition from my about my ears to the ends. This shampoo/conditioner was very disappointing.

Great Hair Products
Purchased

I have just started using Number 4 hair products and have really enjoyed using them. I have fine hair and so far, so this shampoo and conditioner have worked well. They smell good too.

Really works (and smells amazing)!

I really love this shampoo. My hair was noticeably more voluminous and very easy to deal with post-blow dry. Plus, the fragrance is lovely without being overpowering.
