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.

I love this shampoo, it's not heavy, so my hair naturally waves and looks like I spent a lot of time on it. I will be buying this product as soon as I get done with his review!

I really enjoyed this shampoo, however I have thick, long hair and wish I would have had the opportunity to use it a few times in a row. I liked it enough to purchase it and try it for a longer period of time.

Something that Really Works!

This is the first shampoo that I would leave my Nioxin for! I've been using that shampoo for at least 13 years, and never thought I would use anything else. I looked forward to getting in the shower and shampooing my hair everyday with #4 Volumizing Shampoo. It felt so rich, and the results were so great. If you have fine, thin hair don't miss out on this one.
