Ouai impresses in reviews for effective detox shampoo, weightless-yet-smoothing hair oil, and evocative scents like St. Barts and Melrose Place, confirming the brand works for deep cleansing and soft, shiny results. However, multiple reviews flag overpowering fragrance, residue or dryness with continued use, hit-or-miss styling (especially Wave Spray), and packaging issues with thick conditioners—making performance and scent tolerance highly hair-type dependent.

If you are trying to regrow your hair and want to use a serum that you can use on clean hair without making your hair greasy or oily looking this is a great option. Completely dries down from a clear serum and won’t notice it at all.

This stuff is awesome. I have thick almost curly / wavy hair and it helps make it less frizzy. Can throw some of this on my hair and then do a little bun and it’s ready to go in 10 mins with tamed hair. Also, perfect for overnight styling. Delicious smell. This is a product that I will always repurchase and have put my friend onto as well.

I typically love their products in this product is the only one that I’ve ever felt like made about everything else. I’ve been obsessed about the scent is fantastic. She’s sweet. She’s floral. It’s everything you would expect from one of their products. The mask itself. It’s thick it’s creamy. It’s thick just like it’s for thick hair but when I put it in and rinse it out, it doesn’t feel special. It’s pretty mad. I feel like even drugstore brands can make better ones than this so just kind of letdown.

The OUAI Wave Spray is one of the best salt sprays I’ve tried. It gives that effortless beach texture without making hair feel crunchy or dry like a lot of sea salt sprays do. Just a few sprays adds volume, movement, and a natural matte finish. It smells amazing too, which is a nice bonus. Perfect if you want that relaxed, slightly messy style without much effort.

I am completely obsessed with the OUAI St. Barts Body Wash. The scent is absolute heaven…it smells like a luxury tropical vacation with notes of dragon fruit, orange blossom, and coconut. Aside from the incredible smell, the formula itself is really nice. It lathers up beautifully but still feels deeply hydrating, so my skin never feels stripped or dry after rinsing.

Even if I’m not a big fan of floral scents, I usually enjoy the rose ones, but the fragrance of this one was definitely not my favorite. That being said, the body wash formula itself is actually really nice and non-drying. It lathers up well in the shower, and the travel size is convenient for throwing into a gym bag or suitcase.

This curl crème provides excellent definition while keeping curls soft, bouncy, and free from crunch. It helps reduce frizz, adds lasting moisture, and leaves curls looking healthy throughout the day. It's a great styling product for anyone looking to enhance their natural curl pattern with a lightweight finish.

The Ouai Detox Shampoo is a staple for me. I will use it for maintenance about every two weeks or whenever I feel like I have a lot of buildup from products or if it’s been a while since I washed my hair and need a deep clean. Whichever comes first. My hair and scalp feel so clean after using it and I notice my volume is always better right after. I do follow it up with a moisturizing shampoo and light conditioner on my roots because it does make my hair feel dry but with that process my scalp and hair feel so clean and refreshed and unclogged if that makes sense. I even bought the refill so I’m never without it. The deodorant in Cape Town smells so nice and is really gentle on my skin. I use it more for the scent than anything. I’ll use something more heavy duty for sweating and BO then use this on top for the smell alone and it works well that way. The scent is light and earthy. The body and hair sprays were such a nice surprise! They last surprisingly well, especially in my hair, and the scents are SO GOOD. St. Barts is sweet and tropical. It’s really fruity and juicy. Like fruit on the beach. Santorini smells so clean and fresh. It smells like being on a bright white boat in crystal clear water. Ibiza is a warm, sweet, spicy gourmand. I love it so much. It smells like vanilla with cinnamon and a bit of rum but it’s not masculine. I could see this being more of a cold weather scent but it’s also gorgeous on a summer night. They don’t last all that well on skin but I can smell them in my hair for a few hours! Definitely one of the better body and hair mists I’ve tried.

I’m genuinely impressed by this shampoo. I picked it up without expecting much, but it has quickly become one of my favourites. It leaves my hair feeling properly washed without that heavy or coated feeling, and my scalp feels really fresh afterwards.

This smells absolutely devine! It keeps me moisturized all day and the smell lasts for hours. I personally pair it with the St. Barts body wash that way the smell lasts longer. It’s a thick body cream which i really like.

Absolutely delicious smell. It leaves the body feeling smooth and soft. A bit difficult to apply on the scalp and wash out due to it's large sugar pieces, so I use it on my body more than scalp. I feel like it has little to no effect for the scalp here. Quiet expensive, would probably not repurchase.

Absolutely love this product. Sometimes my hair feels heavy and using this cleansing detox shampoo leaves it feeling light and "clean" again, removing build up from other products that weigh the hair down over time. Highly recommend.

Ouai hasta a great variety of body and hair products. My favorite is the detox shampoo, the way my scalp feels clean after every use is amazing. It doesn't feel like super dry either. Everything from this store is amazing honestly

I didn't even know this brand made deodorant but, now that I do, I'm willing to splurge. This smells heavenly. It goes on smooth, doesn't make a mess and lasts for hours. My new favorite product - looking forward to trying the other scents.

I have been using this product for a year and have really liked it! I have wavy (occasionally frizzy) hair and adding it to my hair straight after the shower has helped tame that frizziness. I also appreciate the scent it helps me feel clean and adds another layer to the experience.

I've enjoyed the thick hair treatment masque - great to use weekly. I find that the shampoo and conditioner fragrance is on the strong floral side - it's pleasant but it's not my favorite. The products seem OK for my hair - didn't make it overly dry but wasn't amazing. However, I do LOVE the detox shampoo and have used it in the past. It feels like a deep cleanse of the hair but it doesn't leave your hair feeling like straw. My other favorite is the St. Bart's body cleanser - it transports you to a beach!

I have thin, fine hair that’s prone to oily roots and dry ends, so I’m always a bit cautious with new hair products. But this detox shampoo has honestly been such a win. It cleans my hair really well without making it feel dry, stripped or weirdly coated, and my roots stay fresh for so much longer. The hair mask is also really, really lovely. It’s super nourishing but somehow still lightweight, so my hair feels soft and smooth without being weighed down or greasy. My ends in particular feel so much healthier after using it. And the fragrance — I’m obsessed. I’m very much a “make everything feel like a spa day at home” kind of person, and using these products actually gives me that little self-care moment. It just makes the whole hair routine feel nicer, calmer and more enjoyable. I genuinely look forward to wash day now.

I purchased this product to use once a week for a deep clean. It definitely gets the job done and leaves my hair in the scalp feeling so clean. I double wash because I feel like that as an extra level of cleanliness. The product has a nice smell and is not overwhelming. I have fine hair and I couldn’t use this every day but once a week is perfect.

I’ve tried several OUAI products, from travel kits to full-size essentials. Everything is gentle and effective, and the clean, fresh fragrances really stand out across the line. The OUAI Makes Scents Discovery set and the travel sets are a great way to sample without committing, and while the products aren’t radically different from other high-end brands, they’re reliable staples with really nice scents. In the past, I also tried their Anti-Dandruff Shampoo, which I found quite effective.

I love the Detox Shampoo. It truly changed my hair! I have thick hair and often feel like product gets stuck in it and I can't get it fully clean. This shampoo removes any residue and leaves me with soft shiny hair. Can't recommend it enough!
