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.

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!

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

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.

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 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!

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!

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.

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.

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.

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'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.
