This bar formulated with coconut oil and cocoa butter promises smooth and nourished hair—and, delivers. It's from Ethique, a vegan, plastic-free, and carbon-neutral brand, is suitable for most hair types, and is easily one of the best on the market.

More and more of us are making the move from liquid shampoo to shampoo bars and not just because they are super handy when it comes to traveling but they are great when it comes to sustainability too. After putting several of the best shampoo bars on the market to test and found that the Ethique shampoo bar was easily one of the best.
If you're new to the world of shampoo bars, then this one is the perfect place to start. Packed with nourishing ingredients, moisture and shine are injected into dull, dry hair. It foams up easily and quickly compared to other shampoo bars on the market, and it's also lightweight which means it's super easy to massage into the scalp and right through to the very ends of the hair. This particular bar just works on so many levels. Not only does the Mintasy solid shampoo look visually appealing thanks to its bright green color (hello perfect Insta shot), but it also smells incredible and works a treat, too.
Ethique is a sustainable brand that was created in New Zealand and launched worldwide in 2020. The brand has 12 shampoo bars and Mintasy is our favorite. It’s a brand that prides itself on being completely plastic-free in everything it does, from the products created right through to the packaging that is used for shipping.
The Mintasy shampoo bar costs around $14 / £12 for a 110g bar of soap, which is the equivalent of around three bottles of regular liquid shampoo, so if you're wading on the shampoo bars v liquid shampoo debate, it's definitely something to consider.
It’s available to buy direct from Ethique.co.uk, but it’s also stocked in Holland & Barrett, Feel Unique, Boots, and Amazon. We haven’t seen many discounts available on Ethique, but Feel Unique often has site-wide deals in which you can snap a few up, or if you're based in the UK you can earn advantage points when you shop via Boots.
Ethique shampoo bar: the ingredients
The hero ingredients in this solid shampoo bar Mintasy are cocoa butter, coconut oil, and peppermint extract. It is safe for use on color-treated hair and is also soap-free and pH balanced. It’s formulated with sodium coco-sulfate, which is a foaming agent made from fatty acids found in coconut oil—an alternative to using palm oil.
The use of sulfates is something that divides people; while some like them because of the foaming effect, others don’t because they have been known to strip hair of natural oils and cause dryness—especially in curly hair, which dries faster than other hair types. However, it’s worth noting that all the ingredients that Ethique use are vegan, sustainably produced and sourced, and don’t contain palm oil or petrochemicals. This means that nothing is derived from petroleum.
How to use the Ethique shampoo bar?
If you're new to shampoo bars something to consider is that it's all about the adjustment process. If you want to ditch liquid shampoo and try a shampoo bar then it's worth noting after years of using a liquid shampoo that using a shampoo bar for the first time can be a little strange. After all, we're used to just squeezing a bottle and massing the product into hair. So, whilst doing things differently doesn't always come naturally, it's worth sticking with it as there are benefits.
There are two ways to use Ethique’s shampoo bar—you can either wet it and create a lather in your hands, much like how you’d use a normal soap; or you can wet it and then rub it down your hair.
We would advise starting at the ends and going all the way down to the roots if you choose the second method. But, you’ll have to repeat it around three times to ensure you have enough product to actually massage and cleanse your hair. It's worth noting that it can also cause tangles and knots depending on your hair texture—this is when using one of the best brushes for curly hair can really come into its own.
What's the best way to store your shampoo bar?
One thing we liked was the fact that it’s square, which means it’s easier to grip and less likely to slip and slide out of the hands. When it comes to storage, it’s best to use one of Ethique’s plastic-free storage containers or an alternative soap saver, making sure you allow the product to fully dry out between uses and that it isn’t kept in running or standing water.

What results should you expect with an Ethique shampoo bar?
When we used this shampoo bar we followed it with a regular liquid conditioner. The addition of peppermint extract means that it not only smells really refreshing but also felt as if it was really helping to really cleanse the scalp, too. If you're scent adverse, fear not, the minty scent couldn't be detected after washing.
After using the bar and before conditioning, hair didn’t feel too clean but it was a little bit ‘squeaky’—however, it also felt nourished, cleansed, and super hydrated without being matted or knotty. When people make the change from liquid to solid shampoo some people say hair is left feeling waxy or greasy but we can gladly report that we didn't notice either.
Like every product in Ethique’s product range, the Mintasy shampoo bar comes housed in a fully recyclable cardboard box and it’s also completely plastic-free. The packaging that the bars are shipped in is also plastic-free and sustainable as Ethique uses cardboard and paper to wrap and send product orders.

What are Ethique's eco-credentials?
As previously mentioned, the eco-credentials of both Mintasy and Ethique as a brand are super impressive. The fact that the shampoo bar is equivalent to three whole bottles of liquid shampoo means that not only is it saving on plastic, it’s also saving water and is most likely saving you some money.
Ethique was founded by Brianne West, a biochemist, and entrepreneur, and to this date, the company has prevented the manufacture and disposal of 9 million plastic bottles.
Ethique claims that each bottle of liquid shampoo contains up to 80% water, whereas their shampoo bars don’t contain any. As the brand says, it doesn’t make sense to pay for water in products when there is already water in the shower.
What other shampoo bars and products does Ethique make?
There are a total of 11 scents—including Mintasy—in the Ethique shampoo bar range, which includes citrus to floral fragrances and all with different uses in mind: there are bars for those with oily hair or for those that need a bit of volume, one perfect for shampooing and shaving and even a gentle one for little ones.
Read below for the full range of shampoo bars:

Ethique Mintasy Shampoo Bar: the verdict
Real talk, overall, this shampoo bar seriously impressed our tester. One thing that lets this bar down is that it does contain sulfates, but we managed to overlook that because it was able to hydrate, nourish, and seriously smooth hair while also ensuring it was really well cleansed.
It didn’t cause hair to tangle or clump or become knotty, instead, it was easy to brush through. The added peppermint extract makes it perfect to use in the morning as the zingy scent will help wake you up, and although it’s a shame that scent doesn’t last in the hair, that’s not necessarily a bad thing—especially if you don't like an overpowering smell.
What about concerns with the price?
Yes, the Ethique shampoo bar verges on the more expensive side in comparison to other bars, but it’s also one of the biggest that we tested. And the fact that it doesn’t contain any water means it’s an extremely concentrated formula that is the equivalent of three bottles of shampoo which is a seriously impressive stat.
Overall, we think it’s well worth the money and is definitely something we would spend our money on—in fact, one of our editors now swears by it. The brand’s eco-credentials alone make it a solid choice, but combine that with Ethique’s pledge to plant a tree for every sale and the fact that Mintasy didn’t leave our hair feeling greasy or waxy, and you’ve found yourself a seriously great choice to make the switch to shampoo bars without the awkward transitional stage.
