- 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 live in an area with very hard water, and my hair was starting to look dull. This shampoo uses apple cider vinegar and chelating agents that literally strip away the mineral deposits. My hair felt soft and looked shiny after just one wash. It doesn't smell like vinegar at all—it smells like a high-end spa. Highly recommend if your hair feels weighed down or 'gunked up' from your water or products. The best clarifying shampoo I’ve ever tried. It lathers really well, and also leaves my scalp feeling cleaner than it ever has. I love that it’s sulfate-free but still powerful enough to remove heavy buildup. It’s definitely a premium product, but since you only use a small amount once a week, the bottle lasts forever. My hair feels reborn!

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 is one of the better detox/clarifying shampoos I’ve tried. It does a great job removing buildup from products, dry shampoo, and hard water, but I’ve found it works best as part of a double shampoo. I always use this first, then follow with a regular shampoo, and that combo leaves my scalp feeling really clean without stripping my hair. One tip that makes a big difference: emulsify it between your hands before applying. It lathers much better and spreads more evenly that way. I use it about once a week or every other week, and my hair feels lighter with more volume at the roots afterward. The scent is light and fresh, and it rinses out easily. If you use a lot of styling products or need a true reset shampoo, this one works really well when used the right way.

The scent is amazing. The bottle is easy to grip and use. I only needed to use one squirt of the shampoo and it lathered up my whole head. It left my scalp feeling clean and free of residue.

I was looking for a clarifying shampoo after spending a few months in an area with super hard water. This stuff does work great! Pros - smells nice - really strips your hair and leaves it feeling SUPER clean - lathers well and rinses out easily - not itchy or irritating to you sensitive scalp Cons - it reaaaally strips out my fine hair. Make sure you have a really good hydrating conditioner to follow up with, or your hair might feel super dry. Overall, it works well ant pulling out aall the bad buildup of minerals and products, and I’ll continue to use weekly or as needed with a nice conditioner.

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.

My scalp had become very irritated and oily, and my hair was looking flat and overly fine. Turns out, a new shampoo I had switched to wasn't working with the hard water I have at my house, and I ended up with hard water buildup on my scalp. It was very uncomfortable with my scalp being extremely itchy and inflamed. I learned about OUAI Detox Shampoo as a fix for hard water buildup on the scalp and decided to try it. My scalp felt immediately better after one use. I switched back to my old shampoo at the same time, and within a few days of being back on my old shampoo, and a second use of OUAI a few days later, I was completely back to normal. I now use it once a week to keep the hard water build up from happening again. While a little pricey, the product is only used 1-2 times a week, so one bottle lasts a long time. It smells amazing and leaves my hair feeling incredibly clean and fresh.

This is honestly the BEST clarifying shampoo ever made! We have very hard water and it was ruining my hair, filters and water softeners don’t work and I’ve tried so many different shampoos with zero luck. I was about to give up, then I saw this and decided to try it. I’ve used it three times and it totally and completely fixed my hair!! I cannot recommend this shampoo enough, it’s the best hair product purchase I’ve ever made.
