- OUAI Detox Shampoo - Clarifying Shampoo for Build Up, Dirt, Oil, Product and Hard Water - Apple Cider Vinegar & Keratin for Clean, Refreshed Hair - Sulfate-Free Hair Care (10 oz)

I have oily scalp and roots and dry ends (very long wavy thick hair) this shampoo works beautifully and I’ve tried a lot of different clarifying shampoos over the years but this one is a game changer! The texture is nice almost like honey, it has a very mild neutral scent, it did suds up a lot which is a plus and it totally changed my hair and oily scalp for the better and rinsed out cleanly. It managed to totally remove oil and build up but at the same time didn’t dry my hair out at all so now my hair is so much softer, shinier and has less frizz too. I only need to use this clarifying shampoo 1x a week but I found that during the other days my usual shampoos and conditioners work so much better now. This is totally worth the price in my opinion.

Quick Summary I have fine but thick hair—lots of hair, but it tends to lie flat and get weighed down easily. This shampoo is excellent for resetting buildup and making hair feel lighter, but it won’t magically create volume on its own. It’s best used as an occasional reset, not a volume shampoo. Why I Bought It My hair isn’t thin, but it lacks lift at the roots due to product buildup, oils, and hard water. I wanted something strong enough to truly clean my scalp without permanently drying my hair out. How It Performs on Fine-Thick Hair ✔️ Removes buildup in one wash ✔️ Hair feels lighter and cleaner afterward ✔️ Helps hair stop clumping together ✔️ Improves movement and softness After using this, my hair feels freer and less weighed down, which indirectly helps volume—but it’s more of a clean slate than a volumizer. Important to Know • This is a true clarifying shampoo, not a volumizing one • Apply in sections to save hair & product • Overuse can make fine strands feel dry • Best used once every 1–2 weeks • Always follow with conditioner (mid-lengths to ends only) For fine-thick hair, spacing out use is key to keeping body without stripping moisture. Scent & Texture • Fresh, clean apple cider scent • Thick gel texture • Lathers well — you don’t need much Who This Is Great For ✔️ Fine hair that gets weighed down ✔️ Thick hair that lacks volume ✔️ Dry shampoo or styling product users ✔️ Anyone needing a scalp + buildup reset Who Should Skip or Use Carefully ⚠️ Very dry or damaged hair ⚠️ Anyone looking for instant volume without styling Bottom Line This shampoo won’t add volume—but for fine, thick hair that falls flat, it removes what’s holding volume back. Used occasionally, it makes hair feel lighter, cleaner, and more responsive to styling.

This stuff works super well, while not completely drying out my hair. It also smells incredible! I have curly hair with a scalp that loves to produce grease, yet ends that need all the moisture they can get. I typically wash my hair daily (I know, that's frowned upon) but if I go a day or two without washing, I can get grease going down an inch at least. About a finger length stripe of this shampoo takes care of that build up. It lathers up a bit, and has a nice consistency. The biggest thing is it somehow doesn't dry out my hair terribly, or make it really tangled. It's one of the best detox shampoos I've tried!

It is an amazing shampoo!! I am a grown up woman past middle age and my hair has all the effects of aging, dull and brittle. After one wash with this my hair showed visual signs of life again, shine, bounce, softness and some volume.

This is a great and yet gentle detox shampoo! I think the best part for me was the smell it was something completely different than any other shampoo. It really does feel like it gets rid of all the gunk of my scalp but it doesn’t dry it! I’ve tried other “luxury “ shampoos that made my hair itch like crazy but this one is great for anybody!

This shampoo really works as a detox for the hair. After just one wash, my scalp felt refreshed and free from buildup caused by styling products and oils. It lathers well, but doesn’t feel too harsh or stripping, which is great for a clarifying shampoo. The scent is very pleasant and long-lasting, leaving the hair smelling fresh throughout the day. My hair feels soft, lightweight, and much shinier after using it. I also noticed that it helps extend the time between washes, since my hair doesn’t get oily as quickly. A little goes a long way, so even though the bottle isn’t huge, it should last for quite a while. Overall, it’s a great clarifying shampoo if you want that “deep clean” feeling without drying out your hair.

This is one of my hair care essentials. I have undyed, naturally curly, slightly fine hair. I wash my hair once or twice a week, and as you can imagine with slightly fine hair, the oil (and dry shampoo or other products) can build up. This shampoo is AMAZING at washing away all of that and leaving me with fresh, soft, clean, amazing smelling hair every time. The way I use it, one bag lasts about 10-12 months. Totally worth the money.

My favorite detox shampoo, it works so well. It really gets my hair squeaky clean & gets all product out. Plus the smell is amazing!! It doesn’t dry out my hair and my hair normally gets oily fast but when I use this, my hair looks clean a little longer. I love Ouai products and have been using this shampoo for a while and I don’t plan to stop!

Love this shampOo, get that squeaky clean feeling which some people hate but it isn’t drying at all. Especially paired with a good conditioner my hair feels amazing. I have type 4a/4b hair but I always blowout and straighten my hair. I find if i use this shampoo my hair comes out amazing and super sleek it’s really effective at getting product buildup out. It also smells really good . A little goes a long way, I usually do 2-3 shampoos. The first one to get impurities and the second gets an amazing lather, it seems small but lasts a long time great value.

Awesome product amazing smell

This stuff is so good left my hair so clean and soft and smells amazing

Skulle vara julklapp men självklart något fel med leveransen. Man kommer inte fram till någon support och jag vill ha pengarna tillbaka. Blivit av med över 500kr! Skamligt! Jag hinner inte köpa andra julklappar nu och har inte råd heller. Har varit tveksam till Amazon innan men dottern önskade sig härifrån, nu vågar jag aldrig lita på Amazon igen.

Ottimo shampoo.
