This singular 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. (No strings attached.)

Shampoo Volume!
Sampled

This shampoo was very good. I enjoyed the smell and lather it produced. I could notice the volume increase from my daily shampoo.

Great Shampoo

Really like the thickness of the shampoo and how it leaves the hair feeling. Only issue not great on color.

Love the way this makes my hair feel after using it - the smell is great, too! The pump makes for easy use in the shower and a little goes a long way.

The best so far
Sampled

I received this as a Birchbox sample and I have to say, out of all the shampoos I have gotten so far, this is the best. I have short to medium length hair and a little bit goes a long way. My hair feels clean all day, not just after washing and after spending all day in the Indian sun and pollution, this stuff made all the difference. Nice fragrance, smells clean not all perfumey.

I like this stuff.
Sampled

It smells like I came out of a professional hair salon and my hair is sleek and soft and thick. I really like this stuff and will consider buying a larger bottle.

No. 4 is the best!

I love this shampoo. It lathers to a great consistency and REALLY cleans my hair without overdrying. Gentle enough for everyday use but it does such a great job cleaning that you don't need to use it every day

Great for my short fine hair
Sampled

Scent is minimal, sample size was great, and my very fine hair did appear to have a little more volume than normal. Can't go wrong with this brand.
