Number 4™ Volumizing Shampoo - 8.5 oz

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.

This is the 2nd sample of this brand and I love both of them! I think the cost is a little steep but I would be willing to pay for it for occasional use, not everyday. Smell is great, it is light and leaves my hair so soft!

I really like this shampoo. A lot of shampoos make my hair oily and weighed down and this doesn't at all. I think I will buy the full size. For fine hair I recommend!

I am a huge fan of anything from the Number 4 brand, but this Shampoo takes the cake! I have super long hair that is curly with no texture, so it falls a lot. Not with this shampoo!!!

Smells really good and foams up nicely. Rinses away cleanly. Not sure if I got more volume but like it
