Birchbox Breakdown

This sulfate-free shampoo proves that style and substance aren't mutually exclusive. The sleek packaging and fresh scent are a nod to Parisian flair, while the scientific formula is designed to turn fine, flat strands into rich, full-bodied hair. The brand's four signature Liquid Complexes—blends of natural extracts—work to protect, strengthen, and purify strands without weighing them down.

How to Use

Dispense into hands and rub together to form a lather before massaging into wet hair. Lather and rinse, then follow with Volumizing Condition.

Loved this shampoo - great product. Smells great and leaves hair with fullness and volume without the weight. Great for thinner hair.

Number4 - the best

With thinning older hair, I love this shampoo. It gives your hair enough volume that it can be styled or dry naturally. Rather pricey but worth every penny.

I love my hair after using this shampoo

I have fine hair and this shampoo works really well. I live in South Florida and the humidity during summer really kills me but since I started using it with the conditioner I can tell you that my hair looks healthier and much nicer. The perfect combination of the ingredients and the smell worth every penny.
