This Ethique shampoo bar is one of the best shampoo bars on the market - not only does the Mintasy solid shampoo look visually appealing thanks to its bright green colour (hello perfect insta shot), but it smells incredible and works a treat, too. It’s packed with nourishing ingredients that inject moisture and shine into dull, dry hair and, unlike some shampoo bars, it foams up really easily and quickly and is super easy to massage into the scalp and right through to the very ends of the hair. 

Mintasy is one of about 12 shampoo bars from Ethique, a sustainable brand created in New Zealand that launched in the UK last year. 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. 

Mintasy costs £12 for a 110g bar of soap, which is the equivalent of around three bottles of regular liquid shampoo. 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 you can earn advantage points when you shop via Boots and Feel Unique often have site-wide sales that it would be included within. 

Ingredients

The hero ingredients in Mintasy are cocoa butter, coconut oil and peppermint extract. It’s also soap-free, pH balanced and is safe for use on colour-treated hair. 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 to 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, meaning nothing is derived from petroleum. 

How to use and store

Using a shampoo bar for the first time can be disorientating; we’re so used to just squeezing a bottle and massaging the product into hair, so doing things differently doesn’t always come naturally. 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, starting at the roots and going all the way down to the roots. If you choose the second method, you’ll have to repeat it around three times to ensure you have enough product to actually massage and cleanse your hair, and it can also cause tangles and knots depending on your hair texture. 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, making sure you allow the product to fully dry out between uses and that it isn’t kept in running or standing water. 

Results

We used this shampoo bar and followed it with a regular liquid conditioner. It smelt really refreshing thanks to the added peppermint extract, which also felt as if it was really helping to thoroughly cleanse the scalp, too. It’s worth noting that 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. We didn’t notice that hair had a waxy or greasy feeling, either, which is something that can happen when you make the switch from liquid to solid shampoo. 

Packaging

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 use cardboard and paper to wrap and send product orders.

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, but it’s also saving water. 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. 

Ethique Mintasy Shampoo Bar summary

Overall, this shampoo bar seriously impressed our tester. The only downside 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. Despite the fact Ethique’s shampoo bar verges on the more expensive side in comparison to other bars, 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. 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.
