  • 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).

  • My absolute favorite clarifying shampoo. I use it once every 1-2 weeks, so the bottle lasts forever! This is always the first product in my double shampoo process and helps to keep my hair clean from product build up.

  • 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.

  • I absolutely love this hair oil. This oil works well on wet or dry hair and the scent is very addicting. You just need one to two pumps, I have curly frizzy hair so it's perfect. It defines my curls and helps so much with the frizz.

  • I’ve only tried the hair oil, but it was so good that I went back to buy more. I love the simplicity of the products; they smell nice and work very well for my hair.

  • This is hands down the best clarifying shampoo I’ve ever used. I’ve tried multiple cheaper alternatives, and none of them came close. Most either left residue behind or made my scalp feel stripped and tight. This one actually does what a detox shampoo should do. It deeply cleans the scalp, removes buildup, and resets your hair without that squeaky-clean dryness. My scalp feels fresh and balanced afterward, and my hair never feels weighed down or brittle. If you’re looking for a true reset shampoo that cleans thoroughly but still respects your scalp barrier, this one is worth it.

  • Scent heavy hair and body care products that feel very minimalist. Ouai is what I imagine most West Coast (namely, LA based) pretty girls use on their hair to make it withstand the arid CA weather. That being said, I think their products are pretty good. It's just that the scents are OVERWHELMINGLY strong, though pleasant. Some of us have sensitive noses though...

  • I've really enjoyed this hair oil! It leaves my hair feeling fresh and hydrated without making it feel weighted down. The smell is nice and fresh but not too fake. I use it on my damp hair, after washing and also on the ends of my dried hair. Keeping my hair nice and hydrated!

  • I really like this brand. High quality, a little pricey, but a little goes a long way. I have very thick wavy hair and this conditioner leaves my hair soft with minimal frizz. I use it with the thick hair shampoo.

  • I recently tried Ouai's dry shampoo foam, and I must say I am absolutely impressed! This innovative product completely changed the way I think about dry shampoo. The foam texture feels luxurious and lightweight, making it easy to apply without leaving any residue. It instantly refreshes my hair, absorbing oil and giving my roots a much-needed lift. What I love most is that it doesn’t leave the chalky feeling that traditional dry shampoos sometimes do. Instead, my hair feels clean and soft, with a lovely scent that lasts throughout the day. Plus, it’s so convenient for those busy mornings or when I need a quick refresh before heading out. Overall, I highly recommend Ouai’s dry shampoo foam to anyone looking for an effective and stylish way to maintain beautiful hair between washes. It's a game-changer!

  • The best leave-in conditioner for my fine hair. Provides great conditioning and doesn't make my hair greasy. Worth every penny.

  • loving the scalp serum so far - smells great and doesn't leave any residue. seems to be helping with thickness and hair health as well. love their leave-in conditioner as well, recommend all the products i've tried!

  • I love their detox shampoo; I am a repeat buyer! I love pairing it with the K18 leave in conditioner once a week for a deep clean feel. I just had brain surgery and before I went into the OR, I used the detox shampoo and leave in hair conditioner mask as my “final” wash before surgery. Leaves me feeling clean and don’t need to wash for days. The leave in made my hair super soft, feels lovely! The first photo is of me pre surgery with the detox and leave in. My husband and I both have curly / wavy hair texture and his go to is the Ouai curl creme. I gave it a go the other day and was impressed as well! Love the scent as well. I did go a little bananas with the Thingdrop recently because there were "new to me "Ouai products I have been wanting to try! I am most impressed by the Deodorant! It smells incredible and immediately takes me to a summer / beach / happy place. Obviously, as a Swiftie, I need to try the St. Barts body wash, stand by for review once I deplete what I have left. Out the gate, i do not get the same citrus / coconut top notes like i do from the deodorant. I recently went to a wedding in Cabo and when I hugged the bride on the dance floor, I exclaimed, "You smell so good! What is that!?" It was the St. Barts hair and body mist! A long day of getting ready, nerves, stress, love, dinner, and dancing and this scent LASTED! You had me on the dance floor. If you buy kits within an order of singles, beware, they do not come grouped together. I had to go back to my original order email and see what went with what. Some were even sent in different shipments. UPDATE, I did make some returns and the customer service was AMAZING, SO FAST and NO HASSLE!

  • This shampoo from Ouai that I tried was meant for thin hair and I don't think it worked well for me. My hair has a fine texture but I have a lot of it. The shampoo cleansed too lightly for my liking. I'd like to try a different shampoo line from Ouai to see how it compares.

  • Super Dry Shampoo: Melrose Place There’s a reason everyone loves Ouai’s Super Dry Shampoo. A super powerful nozzle that blasts a fine powder straight for your roots to target and absorb oil, dirt and sweat. It never leaves behind a residue even on the darkest of hair. Melrose Place is my favorite from Ouai. If you’re a Rose lover you will love the fresh, floral fragrance. Forget about a hair perfume, this has you covered! It smells so good I love catching the smell on my hair during the day. Not your drugstore dry shampoo. This is totally worth it!

  • The scent is soft and beachy without being overwhelming. I love using it on my clothes and hair for a subtle refresh. It’s not super long-lasting, but the vibe is effortless and pretty. I always get compliments when wearing this one.

  • I received a birthday gift from Sephora which included a trial size of the Ouai leave-in conditioner. The leave-in smells absolutely amazing and I like that it’s a spray rather than a tub, as many other leave-ins are. The standout product is, in my opinion, their Detox shampoo, which I use when I have additional product build-up in my hair before my actual shampoo.

  • I like this oil but I feel like the fragrance can be a bit intense! Would be amazing for this oil to come in a more subdued fragrance like lavender or eucalyptus even. Otherwise this oil is great for on the go and frizz control!

  • This hair mist has such a tropical scent, it reminds me a bit of a pina colada vibe! The funny thing is that this doesn't have any coconut notes but it smells so much like coconut. I like that it doesn't weigh down my hair or make it stiff or sticky. Really good scent and worth the hype

  • 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
