I’ve Tried Hundreds of Shampoos—This Is the Best for Banishing Grease

As a beauty editor, I am lucky enough to receive samples of some of the bestselling products on the market. From TikTok-viral blushers to luxury designer fragrances and even iconic nail polishes, I've tried it all. As much as I love testing everything out, if you were to ask me which products I would actually repurchase with my own money, I guarantee that the list wouldn't be as long as you'd expect. However, every now and then, a beauty product comes along that knocks me off my feet. Although it would be dramatic of me to say that I couldn't live without this small selection of products, I would go as far as to say that they have revolutionised my beauty routines. Because of this, I always make sure to recommend them to everyone I know.

One product that I get asked about time and time again is shampoo. Before working in beauty, I never really cared about what shampoo I used and would pick up the cheapest one I could find in the supermarket while on my weekly food shop. However, with more and more people interested in how to care for their hair thanks to the rise of the scalp care market, I quickly came to realise just how important this product is for keeping your scalp as healthy as possible. While testing out various shampoos to see which ones I would recommend, I came across the Ouai Detox Shampoo, and now I wonder what I ever did before getting my hands on this product.

Yep, I would definitely repurchase this shampoo time and time again and I've recommended it to pretty much everyone I know. Interested to know what all the hype is about? Keep on scrolling for my in-depth review...

What Does Ouai's Detox Shampoo Do?

Let me start by saying that this is not your normal, everyday shampoo. Instead, this is a clarifying shampoo designed to remove product buildup alongside oil and dirt. The formula contains apple cider vinegar and micellar water that work to remove these impurities and leave your scalp feeling squeaky clean.

The shampoo is also infused with the brand's iconic Melrose Place fragrance. This rose scent features notes of bergamot, lychee, white musk and champagne. My boyfriend always says how good my hair smells when I use this.

Can You Use the Ouai Detox Shampoo Every Day?

Although the brand says to use the shampoo whenever you feel like you need a deeper cleanse, I probably wouldn't recommend using it more than once a week. The reason for this is that the shampoo really does give your hair a good cleanse, and using it every day might leave your hair feeling quite dry. That being said, if you have an oiler scalp or are putting a lot of product in your hair every day, then you might want to up the usage and see how your hair reacts.

The best bit about this shampoo is that it is safe to use on all hair types including colour-treated, keratin-treated and Brazilian blowouts. Just don't forget to apply a nourishing conditioner after using.

Is the Ouai Detox Shampoo Worth It?

So, is this shampoo worth it? I can't tell you how many times I have washed my hair, blow dried it and still felt residue in my roots. However, since getting my hands on this shampoo, I no longer have to worry, as it it easily one of the best clarifying shampoos I have ever used. No matter how much product is in my hair from hairspray to hair oil and pomades and gels, this will always get rid of all that buildup and leave me with fresh, bouncy roots. I've also found that the fresh feeling lasts so much longer thanks to the cleansing formula and beautiful scent.

That being said, it's worth noting that this shampoo isn't cheap. I wouldn't normally spend £28 on a bottle however in my opinion, this product is totally worth it. As mentioned above, I don't use this every day which means that it lasts a lot longer, and you don't need a lot in order to get a deep clean. Overall, if you're someone who uses a lot of product in your hair and struggles to get that "just left the salon" feeling, I highly recommend giving this shampoo a go.
