- OUAI Fine Hair Shampoo - Biotin Thickening Shampoo for Flat, Thin Hair - Volumizing & Strengthening Keratin & Chia Seed Oil for Women & Men - Lightweight, Color-Safe, Sulfate Free, 10 Oz

I love this shampoo. I have fine, short gray hair, and you only have to use a small amount. The effectiveness is great, leaving my hair soft and shiny. I did not notice any smell. I also purchased the OUAI Fine Hair Conditioner.

Wow this is a fabulous product! I have fine, slightly curly hair, pretty thin. This shampoo has been absolutely effective in giving my hair more body, while encouraging a nice curl. My hair looks clean longer, and definitely looks thicker, there is no doubt about it.

It’s a great product, especially for fine thinning hair. I have tried many other shampoos but Quai actually is the best for me. I have very sensitive scalp. It is slightly scented, but not harsh or overly scented.

Love this shampoo and think it does make my hair look fuller and less flat/thin. I love the smell too. Had to order replacement for first bottle because it came with defective top that leaked. Second bottle works great.

I've just started using Ouai, so I can't comment about long-term use, but my initial reaction is certainly favorable. It smells great, but the scent isn't at all overwhelming during the shampoo or afterwards. The shampoo is expensive, but it takes only a small amount to create really luxurious suds. I haven't noticed that my hair feels thicker, but it is definitely softer and shinier, and frizziness has been tamed.

High lathering shampoo with a very small amount needed. It give my fine, thin hair shine and volume. 4 stars because it is pricey.

This is a thick shampoo, and it might take a bit more than other shampoos to use. But your hair feels really clean and oil free after using. Yes, it's a bit expensive, but it's worth the money (my opinion). I'll buy it again.

Over the years I've used so many kinds of shampoo, including volumizing shampoos for fine hair. This is definitely the best. It lathers up so well; it's light; and the fragrance is delightful and not overpowering. Yes, it's a little pricey, but think of it as a special pampering and indulgence for yourself.

good as expected

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.

Best shampoo for fine hair ever and I’ve tried them all.

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

Veey nice shampoo
