Ouai earns largely positive reviews for effective staples like Detox Shampoo, Leave-In Conditioner, hair oil, Air Dry Foam, and Wave Spray that leave hair clean, lightweight, shiny, and well‑scented. Reviews also flag notable drawbacks: overly strong, lingering fragrance that irritates sensitive scalps, hit‑or‑miss performance on shampoos/conditioners and masks (drying, buildup, or just “meh”), and occasional packaging frustrations (stiff conditioner bottles, finicky sprayers).

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.

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’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.

My first Ouai order! I’m glad I assumed correctly, I really like OUAI’s hair and body mists. The scents are clean, modern, and don’t feel overly sweet or cheap like a lot of body sprays can. They last longer than I expected for a mist and are noticeable without being overpowering. I also like that they work well in hair without making it feel dry or sticky, which makes them easy to reapply throughout the day. Overall, they’re a great option if you want something light, versatile, and polished without committing to a full perfume. Cute gift, but the contents in the box did get shaken around a bit.

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 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.

I cannot say enough good things about this, it works wonders and definitely makes my hair feel stronger. It only takes three minutes and it really works so well, it smells amazing too. My hair seems more manageable and has less breakage.

I absolutely love the St. Barts scent line. This is one of my favorite moisturizers and I actually finished it (even though I have lots of half full products to choose from). The texture is perfect for when you get out of the shower and there's a fresh scent.

I have incredibly fine hair that gets oily very fast. I use the detox shampoo once a week to really cleanse my hair of all the buildup my hair feels like all the gunk has been gotten out after using it and looks fantastic for the next two days without any dry shampoo.

I’ve always loved Ouai as a brand mostly because their scents are appealing and unique. A few years ago I had a Melrose Place candle and it hooked me, so when Ouai showed up on Thingdrop I knew it was finally time to try the hair products. I went with the Fine Hair Shampoo and Conditioner and also grabbed a shampoo refill. First off, the packaging is very my vibe. Simple, clean, and looks good in the shower. The shampoo itself is slightly thicker than what I’m used to, but in a good way. It feels concentrated and once you add water it really activates. I usually double wash and noticed a ton of suds even on the first wash, which made my hair feel clean. I also didn’t need much product. The conditioner was lightweight but still moisturizing and didn’t weigh my fine hair down. The scent is honestly the standout. It lingers in my hair way longer than what I expected. I could still smell it 24 hours later, which almost never happens for me. My hair felt clean, soft, and had nice volume without feeling fluffy or dry. Overall, I’m really happy with how my hair looked and felt. I also want to call out their customer service. The refill shampoo bag I ordered arrived punctured and was slowly leaking. I reached out with a photo and they sent a replacement refill quickly and with zero hassle. That alone makes me feel good about buying from them again. Overall, great scents, solid performance, and a really good experience.

The detox shampoo is my holy grail hair product! I use it once a week before my normal routine for a full hair reset and it works perfectly to get old product out of my hair and scalp. I usually get the 3oz size which is great for travel and still lasts forever! The smell is great without be overpowering. The detox shampoo is my holy grail hair product!

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!

This is my third bottle to date! It’s probably the best smelling leave-in conditioner I’ve ever used. I use it most often for its heat-protectant element and apply it to damp hair before drying and straightening. Sometimes the squirting nozzle can get stuck and it’ll spray thicker droplets rather than an event spray, but I don’t mind it too much since I’ll often spray it into my hand and then spread throughout.

I’ve used the Ouai products on and off for 8+ years now. I finally found the fine hair product line and it’s one of the best that I’ve tried. I love the scent but don’t love the fragrance as a product. My husband even loves the products and I got him the full hair line! It’s expensive too but it does last

This detox was a hair saver. From Lake water, well water, products, treated city water… my hair has been thru it. I needed a shampoo to detox my locks! I keep A trail size in my carry on to clean my hair from all the travel woes my hair goes thru. Clean hair is healthy hair.

I like products from Ouai. Initially did not think it was worth the cost, but after trying some products I have changed my mind. Their haircare products are good quality and nicely fragrances. I like that it doubles as perfume/ hair care.

Ouai’s detox shampoo is truly the best clarifying product out there. I live in an area with extremely hard water, while also having naturally blonde hair that can get brassy, dull, and greasy-looking from the minerals in the water. I use Ouai detox 1-2x per week, and notice a huge difference in the color, texture, and shine of my hair. It foams really well and has a great scent. This is a product that will always remain in my rotation.

I use the Detox Shampoo once or twice a week as a deep clean and let me tell you... they stuff gets your hair SQUEAKY. It's great at getting all of the product, oil, buildup, whatever else out of your hair. If you use dry shampoo or hairspray, this will do you well.

I have been using this brand periodically for a few years. It does have a strong smell in the shower, but I don't really notice it outside of that. I like that it isn't heavy on my fine-medium hair, of which I have a lot.
