Reviews

Best shampoo ever

"The best shampoo for thick wavy hair, that gently but effectively cleans my scalp and gets rid of any grit, and oil. Smells amazing too! This is the only shampoo that doesn’t dry out my scalp or make it oily. Perfect balance of everything. Keeps my hair so soft and shiny"

Rachael S. (5/5)

It’s nice

"It’s nice smells good, lathered decent. I prefer the clean feeling of the detox shampoo better"

Lana M. (4/5)

Works great. . . smells horrible

"After falling in love with the detox shampoo I decided to give this shampoo and conditioner a try. I've only used it a couple of times, but I can definitely see a difference in my hair when I use this versus other shampoos- my hair is much smoother and has some shine. But I seem to be the only person that thinks it smells absolutely terrible. I LOVE the smell of the detox shampoo, but this one. . . . it reminds me of the lingering smell of nail polish remover. I absolutely HATE it, and it lingers for days so I feel like I can't get away from it."

Love It!

"I Love this stuff!! I use the whole line. I’ve tried the fine, medium and Thick-All are great, but Thick is my favorite. It smells so clean and fresh! My hair is thick and it can be Oily. I wash my hair 2-3x week and when i do wash it, I do it twice in a row (double wash) I use the Oaui Detox Shampoo 1st then the Oaui Thick shampoo Then I follow it up with the Thick conditioner i leave on a few min, rinse, towel dry and spray in the leave in conditioner-also my favorite leave in conditioner (smells amazing too) and keeps my hair hydrated I get so many compliments on how it ALL smells so good 😊. Ive tried Every single expensive shampoo & conditioner on the market, this one by far will always be my Favorite 1 Thing Id love Oaui to change is the bottles! They need to make them a pump, instead of squeeze. Because the bottle is hard to squeeze! Otherwise I Love I"

"Wowww this shampoo and conditioner are so great already. I have only used them both twice but after the first shampoo & condition, my hair felt so light weight, soft, shiny and just all around healthy. I have super thick hair and all products weigh heavy on my hair but this is great. Doesn't take too much of rach product to get my hair clean and soft. Love it+"
