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 have to say this is the best shampoo I have ever used. I am a hairdresser and have used hundreds of different types of shampoo. The shampoo makes my hair look thicker and smell so good. I don't know any other shampoo that can compare to No 4 shampoo.5
I have fine, oily hair and I'm always on the lookout for a deep cleaning shampoo that doesn't leave my hair flat. This shampoo is the best I've found so far! My hair is no longer oily and it does give volume, even to my limp strands. I'll definitely be purchasing again!5
This is one of the only volumizing shampoos I've ever used that actually gave me more volume5
This is great for fine hair. My daughter has fine stright hair and this did wonders for her. Left it soft with much more volume.5
Love this stuff! Lathers nicely and great smell without being overpowering. My hair feels very good afterwards and soft and clean.5
I can't get enough of this line of shampoos & conditioners. They smell amazing & really deliver on cleansing & conditioning your hair without weighing it down. I have fine hair but a lot of it...this makes it feel light & silky & full of volume.5
A little goes a long way to it will last, smells really lovely.
I have a lot long, fine brown hair and it gave me a lot of volume at my crown. Loved it. Conditioner is nice too!
Not sure if it gave me more volume since that's not a problem for me but I love the smell of the shampoo. and leaves hair fresh and clean.5
I loved the extra volume. I also had the conditioner which worked great too.5
Hi have super fine, flat hair with no body. I use this shampoo every other day and it really gives texture and fullness to my otherwise lifeless hair. I like that I can go a day in between washing with no greasy build up. In fact my hair looks best the second day. My hair does indeed feel thicker. It also has a great scent that lasts all day.5
