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."

Shampoo is nice, smell is offputting

"I have many Ouai products and have loved them all ESPECIALLY the scent of them. So much so that I have several of the perfumes and body sprays so I expected to love this shampoo. The scent of this is very old lady powdery, perfumed not like the natural, clean, amazing smells of the other products. I washed my hair once with it and it lasted for DAYS. Even after I washed it again with another shampoo. It is not good. I’m sad about this because I love Ouai products. I will keep using the other ones I have already."

"I’ve bought countless high-end shampoos and conditioners during my hair health journey. And I have never once noticed a difference between brands or formulas. Never once said “this is worth the money”…. Until now. I have naturally wavy/curly (2C/3A) hair. I use a lot of products and diffuse my hair each wash day. My biggest priorities are a CLEAN scalp and moisturized hair without being weighed down, this checks every box twice and more. The shampoo lathers and cleans so well. The conditioner moisturizes, softens and adds so much shine without a greasy feeling and without weighing my hair down. Buy this. You wont regret it."

Love it!

"This product is a life changer. I have fine curly hair, and anyone with this type of hair knows it is hard to find products that work well. I love how healthy my hair is as well as the fragrance of each product. Absolute game changer."

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!"

Best shampoo

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

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!"

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 :)"

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."
