Leaves hair soft and smelling great
Great for fine hair. Leaves you head feeling soft and great smelling. If your hair is feeling dry or in need of some TLC, do not hesitate to buy

Good shampoo for fine hair
This is a good shamooo for fine hair, it leaves my hair feeling light after every wash. But this needs to be used with a conditioner, otherwise hair will be dry

Gorgeous on hair in dire need of a boost.
It's magic on highlights. This duo shampoo and conditioner is out of this world - it has given my hair the curls I used to have, the volume is miraculous and the shine - but most of all it enhances the highlights in my hair. A bit pricey but generous in size. MAGIC

Great smelling shampoo for fine hair
Adore this shampoo, it absolutely scrubs my scalp that’s prone to greasiness because of my fine hair. I feel like I get great volume after use and it smells great

It works!
I use this all the time together with the Ouai conditioner for fine hair. It does make my hair feel much thicker with more volume.

Lovely shampoo
Nice gentle shampoo. I haven't particularly noticed it making my hair appear any thicker, but it certainly makes it look silky and soft and I enjoy using it. I've been using it non-stop for the last six weeks and I haven't noticed any build up on my hair. Five stars is because I'm not sure why this brand design all their bottles like this; you need the strength of a bodybuilder to be able to squeeze the product out (and if you resort to your knee and the side of the bath to squeeze it out you end up with a creased-looking bottle). Instead I just unscrew the cap and tip some into the palm of my hand.

Shampoo indicado para pelo fino.
La descripcion del fabricante da a entender que es un shampoo para pelo grueso. Es todo lo contrario, indicado para pelo fino y con poco volumen, realmente lo levanta, tal vez lo seque un poco asi es que si el pelo es fino con poco volumen y con tendencia grasa es el ideal.Estoy de acuerdo con otras reseñas que la fragancia no es de las mejores y muy intensa,esto deberis tenerse en cuenta ya que a menudo las alergias pueden ser producidas por los perfumes.
