Reviews

Best shampoo

"Best shampoo I have ever tried for my fine and thin hair. However the bottle is horrible. But the shampoo is so good I don't care how bad the bottle is. I just transfer it into a better squeeze bottle."

— Dixie (5/5)

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)

Best shampoo

"Besides smelling absolutely amazing, it preps my hair for any treatment, and my curls feel soft, clean, and super fresh."

— Meredes P. (5/5)

Love it! Love it!

"I love this shampoo. I’ve tried many (too many) shampoos for “fine” hair. This is the only one that actually makes my hair feel thicker. I’m a customer for life! Also, I love the scent. The next day after washing I can still smell the Mercer St scent. I wish Mercer St was in more of your products. I hesitate to use, the conditioner, and the styling products because their smell will over write the Mercer St. But the shampoo for fine hair is truly wonderful!"

— Born 🥴. (5/5)

Good Shampoo, Great Scent

"Pleeeaaseee bring back Mercer Street perfume. I need to sentmax this fragrance lol! Oh the shampoo? It and the conditioner are good mid range products. They’re not bad but it doesn’t blow my socks off. I find myself reaching for them tho, and I’ve finished their travel sized products (which is my rule if I am to purchase full size). I have fine wavy hair and it cleanses my hair really well and the conditioner doesn’t weigh it down. Are there drugstore shampoos that do the same? Sure. My shower experience is also important to me though, and this scent is heavenly. After 12hrs post shower and even sleeping on it, I can still smell the scent, and in this case, I love that. My hair feels soft and airy, thank you Ouai :)"

— Rainie (4/5)

Best I’ve had

"I have fine hair that tangles with all hair products. Ouai is hands down the best at not making my combing experience painful and smells great."

— Suzanne S. (5/5)

Love the shampoo & conditioner

"Ouai smells so good and leaves my hair looking great!"

— Jennifer F. (5/5)

Great shampoo

"I have tried a lot of shampoo and conditioners for my fine hair and this has been the best product I have found."

— Elizabeth S. (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)
