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).

  • Absolutely love ouai. When I first tried out this brand, I tried the leave in conditioner and I hated the scent! But after just a few days I started to fall in love with it. I have tried the leave in, detox shampoo, wave spray, texture hair spray, and dry shampoo. Every product smells absolutely amazing and very luxurious and I love the simple and clean packaging. They also work sooo well too. The leave in conditioner and the texture hairspray have got to be my favorites. The leave in helps detangle and makes your hair smell so good and feel soft. The texture hairspray adds body and hold but isn’t sticky or gritty. I can’t wait to try more from this brand.

  • Their leave-in conditioner, hair oil, and detox shampoo are game changers. Great smell, effective, and clean.

  • I love the OUAI apple cider vinegar shampoo. Its brought out my natural curls and helped with hair loss.

    Offer a bigger size

  • Everything I’ve ever tried from this brand is perfection. Love the travel sizes for when I want to try a product!

    The price - but it’s worth the money. The smell is not for everyone

  • I like most of their products. Hairspray smalls good. Same with the dry shampoo moose. The dry shampoo spray didn’t work that gray for me. I’m a super light blonde so these matter to me.

  • A little pricey for sure but their products are also worth the money. I love the leave in conditioner (works as a heat protectant too). Looking forward to trying their perfumes soon!

    Lower the price!

  • Personally I am a huge fan of their hair oil. I have medium length, thick hair that I semi-regularly bleach and dye and it always leaves my hair feeling smoother.

    Feedback

    It's got a strong scent which I feel like could be toned down some. It's also fairly pricey so if you're on a budget I'd recommend looking elsewhere.

  • I tried the Fine Shampoo and Conditioner and didn't have an outstanding experience. By no means was it terrible, but it also wasn't impressive. It made my hair feel dirty/greasy relatively quickly (I definitely could not have gone multiple days without washing). Maybe I didn't have the right one for me, but for the price tag - this was not worth it.

    The Thin Hair shampoo and conditioner could definitely be optimzed

  • The products feel luxurious. I have tried a few of their products (such as the Wave Spray and Air Dry Foam) and really enjoyed using them. I have other favorite products that I tend to reach for more, but these are definitely in the mix. I have a few products that are on my wish list for future buys.

    I really enjoyed the products that I have used from this brand, however there may be an option to make mini/tester sizes given the price tags are more in the luxurious spend items than everyday.

  • LOVE their Fine to Medium hair mask and their body creme. Everything smells so good and actually works. My hair has never felt softer!

  • I absolutely love their leave-in conditioner! This product smells amazing and leaves my fair smooth and ready for styling.

    Cost

  • In love with their shampoo for fine hair! Deep cleansing and rich lather. Also love their hair oil, leaves my hair shiny and smelling pretty!

  • I LOVE OUAI! I use the thick hair shampoo + conditioner and will never go back. I've tried Olaplex, Briogeo, Amika, all the things. Ouai is the only one that made my waves bounce and shine with 0 effort. I am a l-o-y-a-l customer! Also, its clean!

  • The only product I have tried so far has been their fine/medium hair mask. My hair was so silky coming out of the shower and it made it less frizzy. After almost a week later, my hair is still super soft, so definitely hydrated my ends.

    Feedback

    I would like a smaller size of the products so I can try it without buying the whole thing.

  • I own the hair oil, texture spray, and dry shampoo.

    Feedback

    Texture spray and dry shampoo are fine. The real star is the hair oil!!!! I have fine, dry hair and I can't live without the hair oil now. I even bought minis to have on the go and in my desk at the office.

  • Nice products, I preferred the styling over the shampoo/conditioner which weren't quite rich enough for my hair. Might try again in future.

    Feedback

    The conditioner wasn't rich enough to moisturise my curly hair.

  • This leave-in conditioner works really well! It makes my hair feel soft, smooth, and much easier to detangle without weighing it down. The scent is amazing—light and fresh, not overpowering. A little goes a long way, which is great. My only complaint is the price—it’s a bit on the expensive side compared to similar products. Still, the quality is undeniable, and I’ll likely repurchase, but I wish it was a little more affordable!

  • Am I going to commit a sin by admitting Ouai isn’t anything special? Probably. But I found it mediocre. I bought the fine hair shampoo and conditioner. The scent? Amazing. Loved it. The cleansing power of the shampoo? Eh. It was okay. I feel cleaner after using cheaper products from Target. The conditioner was better. Not too heavy, smelled nice, but not enough of a wow factor to justify me buying it again. After using the entire set up completely, my hair felt like I needed to do a deep, deep clean. Even after it was freshly washed, I felt like I needed to wash it again. And the cap to my shampoo broke halfway through the bottle. I’m sure that’s a fluke, but still super annoying.

  • The St. Barts scent is AMAZING! If you’re a vanilla girly then this is for you! Feels good on your skin going on, and your skin feels amazing!

  • This is a high quality product. These products are a little expensive but worth the price. I love the scent of all the products that I have tried from this brand. The scents are strong but not overwhelming.
