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.
AI summary based on Thingtesting reviews
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!

I like the product (leave-in conditioner) but I think it's a matter of liking the product because I want it to work? if that makes sense. I primarily use the leave-in conditioner as a heat protectant when I dry my hair but it doesn't do much to reduce frizz. Also, because I have thick hair, I have to use a lot of it in order to get the full effects.
Feedback
Maybe include a pump rather than a spray pump; I feel like when I spray the product, about 50% just ends up on my counter or in the air. I also wish it was more affordable; I'd like to try all of the other products but I only buy this conditioner when it's on sale.

Hands down the best hair oil and leave in conditioner I've ever tried. Lovely smell, worth every penny.

Shipping is a bit slow.

I got the detox shampoo about six months ago and will never buy another shampoo again. It has helped improve the texture and strength of my hair and I've noticed a significant decrease in split/dead ends in-between haircuts. It's so good that I decant it into a small bottle when I travel so I can avoid all other shampoos. Plus, it lasts really long! I'm barely halfway through the bottle and I wash my hair every other day.

It's always out of stock!

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.

For years I’ve been using the body scrub/exfoliator and the hand lotion. The lotion comes in a nice white bottle that looks nice in my kitchen and I like the smell and smooth consistency of it. The exfoliator is super nice for dry skin and I keep it in my shower.

I love their detox shampoo: it makes my hair feel really clean. And I also love their hair oil. It adds shine and hydration without weighing down my hair! Their leave-in conditioner is also AMAZING and smells so good. I am updating my review to include the scalp and body scrub. I loved the texture and that it didn’t irritate or dry out my skin. However, it would break me out. Every single time I would use it, the next day I would have a pimple/clogged pore (usually on my arms but sometimes my legs). It was the day after I would use it without fail, so I know it was this product. I won’t repurchase the scrub but will continue to use their other products. I’m also loving their new Ibiza hair and body mist; it’s a warm, comforting scent perfect for summer!

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 love The Ouai leave in conditioner. I have fine hair, so sometimes it's hard to find the balance between moisture and stringiness. This leave in definitely finds the perfect level of moisture for me. And it smells good!

Definitely on the more luxurious side of shampoo - I absolutely love how it makes my FINE hair feel. I always feel extra clean, and the lather is great on it. I also SWEAR BY the body butter - especially in the St. Bart's scent. I would bathe in it if possible - and makes me feel moisturized.

Best hair spray for waves! Smells great, it is super light, defines the curls and the waves, doesn’t leave residues and it is my family’s favourite ( mom uses it as well)!

Wow this bodywash is so epic I can’t stock up enough. It smells so so good and makes me want to shower 3 times a day. The lather is like nothing I’ve ever felt before and is so think and lovely! This is a highly recommend from me and I will always repurchase. A spa day at home for sure! Love Love

I wasn't sure about the price per oz on this product but decided to give it a go and have been extremely stoked on it. I got the leave in conditioner but am now curious to try others. I have pretty fine medium length hair and just need 2-3 sprays - it doesn't weigh down my hair but does the job.

The scent of the leave in conditioner is a little much. I actually used it to confirm when I had COVID because it is so ridiculously strong and when I couldn't smell it at all, I knew I was positive before I even tested.

I use a natural, plastic-free shampoo bar 90% of the time that I wash my hair. This is made possible by Ouai’s detoxing shampoo. It gets my hair crazy clean and detoxed so that I can go another month using my hippie-dippie hair products.

I would love a nicer scent.

This! This leave in conditioner spray is an amazing product. Smells amazing, works well, travels well...all the things! If you're looking for a conditioner - look no further. You need this! It won't disappoint!

I only use, shampoo and conditioner for fine hair and every now and again, the Detox shampoo as well. I really like them, pricey but worth it. Cleanses really well and hydrates at the same time. Absolutely amazing smell. I use products for find hair.

This is quite a treat for me but it's worth every penny.

Can't say enough good things about OUAI! I've tried so many products and these are hands down my favorite. They have so many unique products that actually work. Also the fragrance on these are all AMAZING. Here are some of my go to: Rose Hair + Body Oil - I love a 2 in 1 especially for travel! The smell is to die for Wave Spray - I use this as a wave spray and a hair refresher! The smell is great for that 2-3 day post wash hair Melrose Perfume - this scent is in a few of their products and its great for everyday wear Hair Mask - I have the fine to medium one and its great Hydrates my hair without weighing it down
