Reviews

Wonderful!

"I really love this product and I’m so grateful it has a refill! I have fine hair and many products weight it down or don’t wash out well but this shampoo is perfect! It leaves my hair feeling healthy, clean and light! I have no issues getting volume in my hair while styling!"

— Katherine A. (5/5)

Wish I had started this earlier

"As a woman in the middle of perimenopause my hair has changed. I have long, straight hair and hormone changes have left me with some hair loss and dryness. This stuff has transformed my hair within a few weeks. I have never had a shampoo and conditioner combo that I love, I find myself always looking for what is popular or what my salon uses. This will be my go to from now on!"

— Kimberly S. (5/5)

"As someone with a lot of thin, straight hair, I’ve gotta say the Ouai fine hair shampoo has been the best shampoo to grace my scalp! I use this one most days, and every few days will switch it up and use the Ouai detox shampoo. Was excited to see they came out with a jumbo pump!"

— Allison (5/5)

Great shampoo

"Ouai shampoo for fine hair is great. Leaves my hair feeling better than other shampoo I've tried."

— Jilna K. (5/5)

This shampoo cleans your hair

"This shampoo cleans your hair so nice. Great fragrance which smells clean too. Great quality shampoo which just a little amount cleans your hair. M"

— Liesl O. (5/5)

"Gorgeous scent and works even better than it smells!"

— Amy (5/5)

It’s the ‘Quai’ for me!

"Wow, at last, a shampoo for my baby fine hair that adds life and lift."

— MICHELE P. (5/5)

Way too drying

"I love the Detox shampoo, but this fine hair shampoo is way too drying. My hair looks awful and brittle."

— Sandie B. (1/5)

The best fragrance EVER!!!

"I bought this for my own hair ravaged by medicine and the fragrance hit me first…the smell was lovely and I fell for it immediately. I wish you had a body lotion with the same fragrance and if you make one…many folks will buy it too! Hope in a bottle."

— Catherine E. (5/5)

Burns my eyes even after my hair is dry

"I LOVED the way my hair looks, but my eyes have been burning since I used it. Even with my hair dry. Not sure what is in it, but be careful if you're sensative."

— Kimberly S. (3/5)

Q&A

what fragrance is the fine hair shampoo?
Hi Carol! Our Fine Hair Shampoo has the Mercer Street scent which is a sheer and airy floral/musky fragrance with notes of Italian Lemon, Turkish Rose, Jasmine Sambac, Iris, Lilly, and White Musk.
Is it safe to use for color treated hair?
Hi Lani! Hope you're well! All our shampoos and conditioners are sulfate free, so they’re safe to use on color treated hair. The PH of our Shampoos range from 5 to 6 and Conditioners range from 4 to 5. These ranges are at the optimal level for hair and scalp health. Hope this helps!
Is the packaging recyclable?
Hi Kay! You can recycle part of your refill pouch. The caps are recyclable, but the pouch had to be made with a type of light plastic that is still OUAI more sustainable than a liter bottle. This part is not recyclable. The plastic these use are 60% less plastic than rigid plastic bottles and require 50% less energy to produce. These pouches also generate less CO3 emissions during production and shipping. They also weigh less than a typical plastic bottle, which helps reduce the carbon footprint in regards to transport and manufacturing.
Do you get more in the pouch than the bottle?? It’s double the price. Thanks
Hello Nicholas! Yes, definitely! Our bottled Fine Hair Shampoo bottled contains 10 fl oz / 300ml of shampoo while the refill pouch contains 32 fl oz/ 946ml. It's triple the amount so you can save more if you're going to refill your original bottle.
