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)

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)

Leaves my hair brittle

"I really loved the smell and I wanted to like this shampoo but unfortunately, even combined with conditioner (and sometimes hair mask), this shampoo leaves my hair brittle compared to other products I have used"

Christina L. (3/5)

Love it in a pump!

"My favorite shampoo! I don’t like the other bottles, it seems to keep leaking out but this bottle is great."
