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.
Best smelling shampoo I've used. Fresh scent and cleans without residue. Love it!5
I don't use volumizing products much anymore due to hair moisture being my main priority lately. Island hair tends to have volume due to wind, but this was a nice product to try. Added more bounce to my hair.3
This shampoo is really thick and I had a hard time getting it to lather. It also didn't rinse out very well, and it added extra time to my shower to make sure it was all rinsed out. It smells really good, and is probably better for girls with short hair. But I don't see myself buying this product in the future.3
In love with the smell! Leaves my hair full and soft and smelling so sweet and clean! I love all no.4 products!5
I like to use conditioner and shampoo from the same brand together and I only recieved the shampoo. I used this with my normal conditioner and this is an effective volumizing shampoowith a good smell.3
Great smell and works well. I like that it doesn't weigh my hair down.
I would recommend this product to my friends definitely!
This is the third shampoo I have received from Number 4 and I have loved them all! This shampoo does what it says it will. It gave me great volume and softness! Keep sending these samples my way Birchbox!!!5
I really love this stuff!!! Wish the sample was a little bigger but it's great! I will definitely try the other products in the future!5
I really did not like the way this shampoo made my hair feel. It felt strawish and I did not particularly like the smell.3
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!5
