Reviews mention

  • Luxurious signature fragrances
  • Effective clarifying shampoo
  • Lightweight, shine-boosting hair oil
  • Versatile, high-performing stylers
  • Overpowering fragrance intensity
  • Inconsistent shampoo performance
  • Occasional drying, buildup issues
  • Fussy, inconvenient packaging

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 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.

  • 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.

  • 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. 🏝️🛁

  • I usually really like Ouai products but this was a fail for me. It is heavy on the hair and does not control the freeze - even a little bit. It is unfortunate because I really wanted to like this product as much as others.

  • I personally use the perfume line from way because the price is very affordable and the fragrance is very bouquet and light. The travel size bottle is perfect for my every day needs that way I can pack it away for trips, but I also get the most out of a bottle without breaking.

  • 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!

  • I really tried with this product I heard that the brand was great for hair like mine to reduce fridge and at shine and gloss to curls. As usual with a new line I buy a travel size product to ensure it works before investing in full size bottles and I'm glad I did as ouai is not for me. I used to they're leaving conditioner, about 75% of the bottle and I have to say I'm not one occasion did I like the way my hair turned out. It felt sticky and ineffective. I have heard good things from other users and I passed on my leave-in conditioner to my sister who has wavier hair and less Cruise less of a course texture and she says as long as she doesn't use too much it's not sticky and she likes it.

  • I honestly love every single product I’ve ever tried from Ouai. But their leave-in conditioner is the one product I absolutely cannot live without. I’ve tried many other leave-in conditioners, but no other products compare to this. It’s the perfect spray where it isn’t too fine where it doesn’t make a difference in your hair yet not too heavy where it would weigh your hair down. Plus I love the clean and light scent it adds!

  • I love the detox shampoo since I have a dry scalp and live in Texas where it’s very humid makes it extra greasy. It does make you scalp feel a bit dry so only use this once a week and use another shampoo for a double wash!

  • I've used Ouai's shampoo and conditioner for a few years now, and my hair has definitely looked healthier and shinier. I like most of the styling products I've used, but the price point isn't always the greatest.

  • I love this soap so much! like at first it felt a little expensive for a handsoap but I bought it when it was core pandemic times and all we were doing was washing our hand. It exfoliates and feels so luxurious. I am not a complicated person so the fancy skincare routines make me crazy. Instead this allowed me to bring luxory into something i do legitamently multiple times a day

  • Big fan of the St Barts and Melrose scents. Love the fine to medium hair mask (HG status) and the detox shampoo is really nice. Not drying and doesn’t strip but hair is clean and soft. I want to try the shower gel!

  • I bought this after I saw a girl on tiktok show her curly hair routine and I was immediately sold. I think this is my 3rd purchase of this product and honestly I love the results of that it doesn’t weigh my hair down but also the fact that it smells so good

  • Great products that are fun to use and help Us stay refreshed and clean. These are valuable to our skin and beauty regimen and I don’t know where we would be without them in our shower! I love the ingredients and size of the container for long lasting use.

  • Their spray on leave in conditioner is an amazing product that’s perfect for travel. I’ve brought it with me to both beach and city adventures. When most hotels will provide shampoo and body wash, not as many provide a really great hair conditioner that I know will work my hair. This is great for that scenario

  • I'm on my 4th or 5th bottle of this hair oil, and I absolutely love it! My scalp is very dry typically so I can use this pretty regularly without ever getting too oily. I'll continue to re-purchase this.

  • I love all of their fragrances, so across the board, they are all a huge win! That said, they are powerful! I use the Detox Shampoo as well and like it, it feels less “harsh” than others like Olaplex, so it doesn’t get as deep of a clean as I think I want (maybe that’s good? lol). The fine hair conditioner and fine hair mask also seem to provide great hydration without weighing my hair down or making it greasy!

  • I’m all about the OUAI St. Bart’s scent! It truly smells so wonderful and relaxing! I bought these “chill pills” bath bomb which are so cute and would make such a fun gift! I think I’d just like them in the other scent!
