Reviews

Love it!

"I initially got the smaller bottle of this shampoo because I wasn’t sure if I’d like it because I have a sensitive scalp. Ive now been using this shampoo and conditioner set for almost a year now and I love it. I have thin hair and this shampoo makes my hair feel so clean without weighing it down. It doesn’t irritate my scalp at all either which is a huge plus. I now buy the larger bottles and i recommend it to anyone who hasn't tried it."

— Rebecca (5/5)

Smells SO good

"I was traveling with a friend about 3 years ago and she had this shampoo/conditioner. I ordered my own before I even used it because it smells incredibly good. But then I became a regular user and boy howdy! do I love how it makes my fine, 2c curls look and feel."

— sav (5/5)

Should have different scents available

"They should make this shampoo in different scents. The Ouai products I had used before were the Melrose Place scent which I love. You can’t smell the different scents even if you find them in a store because they are sealed so I decided to just buy it and try it out, and I’m sorry I did because I don’t like the scent at all."

— Erin B. (2/5)

"The best thin hair care regimen I’ve EVER used, (I’m in my mid-40s) If you have thin hair, you’ll be amazed. I promise. The smell is so good, I’d wear it as perfume 😘"

— Mandy (5/5)

"I am extremely impressed with this product; it is ideal for thin hair, and the fragrance is exceptional.🥰🥰🥰 and I'm so happy with the free pouch! 👝"

Best Shampoo Ever

"This stuff smells wonderful and I love the way it makes my hair look and feel! Just have to go really light on the conditioner or it will leave your hair a little oily"

— Pamela G. (5/5)

Best shampoo for fine hair

"I have tried so many shampoos for my fine hair, but always come back to this one. It leaves my hair feeling healthy and “full of life”. And the scent is incredible."

— Edita C. (5/5)
