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.

I'M IN LOVE AND WOULD REPURCHASE THE HAIR OIL A MILLION TIMES OVER. every time i wear this oil on my ends, people compliment me twice on both how my hair looks and how i smell. I have bleached blonde ends and this is the only oil that's weightless enough to not weigh down my fine hair but also give me incredible shine.

The first thing I noticed about this shampoo was the scent. It’s not as heavily scented as some of their other products. Neither good nor bad, just something I noticed right away. It has a very light, clean scent that doesn’t linger. The first time I used it, I didn’t feel like it left my hair or scalp very clean. But I started to double cleanse and it has made a huge difference. It foams up really nice and rinses out clean. My hair feels lighter, and my scalp less itchy. The only real con is that it left my hair feeling a little dry

I love everything about this hair and body mist. The St. Barts scent is intoxicating. It has a fresh and fruity fragrance with strong notes of coconut. It really captures the tropical vibe. Great product! Love the leave in conditioner and scalp scrub too! I’m excited to try the deodorant I just ordered.

I wasn't sure what to expect from this "salt" spray. I have naturally wavy hair, but it's thick and needs help. I've tried other products from Ouai and always liked how glossy they leave my hair. After using this on damp hair, I wasn't sure it did much at all. It dried, and my hair looked super shiny, but not too much wavier. The next day, however, my hair looked SO good, healthy, and shiny! I am officially a fan and highly recommend to other wavy haired people who struggle with frizzing and dullness.

Their Detox shampoo is excellent - lathers super well and smells amazing. I feel like it gets my hair and scalp squeaky clean, while leaving my hair soft and glossy. It's ideal for that reset wash of your hair when you can feel that buildup, etc.

I’m addicted! Love this brand! The hair serum works wonder, the volume spray actually gives me volume… and the perfumes are the perfect scent! Yes! Yes! Yes!

I have only tried a few of their products but have loved them all. The leave-in condition made my hair so soft & healthy. I use it every time I style my hair, heat or not. I’ve been sampling the anti frizz crème and so far I’m a fan. I have no doubt their wave spray will be a new favorite. The Detox shampoo is a must buy. I use this once a week and it truly clarifies your hair from any build up.

I love the leave-in condition, especially for air drying my naturally wavy hair.

I love Ouai's packaging, minimalist branding, and wonderful scents, but the actual benefits don't stand out to me. The wave spray does add texture to my wavy hair, but it also makes it frizzy, and overall does not improve my hair's appearance. I want to love the products, because the brand itself does a great job of marketing, but I just can't bring myself to repurchase.

The products are pricey, but I’ve loved all I’ve tried. The detox shampoo deep cleans without drying, the leave in is lightweight and hydrating, the wave spray enhances curls without being crunchy. All the products smell amazing and they even having matching perfumes!

As someone with incredibly fine but THICK hair (aka fine strands but LOTS of em) who also suffers from incredibly oily skin, the Detox Shampoo with the Fine Hair Conditioner has been a LIFESAVER!! After getting fed up with my usual high-ish end hair care, I bought travel sizes of the products to try them out on a whim - I am NEVER going back (much to my wallet’s dismay)!!! I’ve never been able to go more than 24 hours without washing my hair due to oil, but since the switch last week I’ve been able to go every other day (huge!!!)! Using a handheld scalp scrubber to really work the detox shampoo in, my hair is so squeaky clean! The conditioner also hydrates and nourishes my fine strands without weighing them down or making them oily. Although it’s pricey, I fear I’m sticking with Ouai because my hair has never felt cleaner or healthier!

El exfoliante de OUAI para cuero cabelludo y cuerpo en la versión St. Barts huele increíble, como vacaciones en un frasco. Exfolia suavemente sin resecar, dejando la piel súper suave y el cuero cabelludo limpio y fresco. Es un lujo sensorial total. 🏝️🛁

This brand is the best. I love all their hair products and will always repurchase. The shampoo makes my hair feel clean and healthy. The difference is noticeable compared to other high quality brands.

I think I generally liked Ouai's products, for example, I've tried and repurchased their fine hair shampoo, I think it does work for my thin, fine hair and for me, the results are better than other similar products.

I got a sample at ulta to try some Ouai leave in conditioner and it was nothing groundbreaking. The scent is nice but this brand is way to expensive- I can get the same quality for much less money at the drugstore

The OUAI Leave-In Conditioner has honestly been such a good find. It makes my hair way easier to brush through and leaves it soft without feeling heavy or greasy. I also like that it has heat protection built in, so I don’t feel as bad about using my blow dryer or straightener. The scent is so light and clean, it's such a luxurious scent, and a little goes a long way, so the bottle lasts. It’s definitely on the pricier side, but it’s one of the few hair products I keep repurchasing.

I first tried the Mini Ouai Cleansing Scalp & Body Sugar Scrub in Melrose Place as a sample and loved it so much. Sephora has a super cute Mini St. Bart's Body Set currently so I purchased a scrub in St Bart's to go with it. While I love that I can take these with me as a travel set and the bag is a nice bonus I do like the Melrose Place scent better. As I run out I may restock my travel kit with the Melrose Place equivalents instead. Still, I feel luxurious packing my little fancy set for vacation and it smells like a tropical vacation.

I've honestly loved every Ouai product I've tried, but the detox shampoo is my favorite. I'm a once-a-week hair washer except during the summer, so I use this almost every wash to get out any buildup from dry shampoo, styling products and sweat. It's way more gentle and less stripping/drying than every other clarifying shampoo I've tried. And the smell is divine ... no wonder they sell it as a perfume now! When I use this my scalp feels clean and fresh but still moisturized and not overly dry, and my hair feels soft instead of like straw, which has been an issue with some other detox shampoo products. Highly recommend! (And pairs great with the Ouai dry shampoo when you're trying to stretch between washes!)

The detox shampoo is a great product when you need to deep clean your hair from toxins and chemicals that other shampoo products leave behind. Plus, a great smell to boot! Def will purchase again, when needed.

Sephora’s finest! Felt like I needed to try due to all the samples they’ve been throwing at me. It’s not for my bleached hair at all. Not necessarily saying it’s bad. And I used the conditioner. It felt like shampoo on my hair there was no softness. Might work for naturals. Love the smell though :)

The Ouai is one of my favorite hair care brands. They have incredible scents, St Barts is my favorite! I have tried many of their products and have not been disappointed. Their shampoo and conditioner is great for my hair and I love that they have different options for fine, medium, and thick hair types. Their soaps, lotions, and perfumes are also all incredible products with such nice scents. The favorite part about the website is that you can shop products filtered by your favorite scent!
