Shampoo Bar - Beer & Rhassoul Clay


The beer shampoo bar is perfect for normal to thin hair. The special formula of organic oils, beer, and rhassoul clay gives your hair an extra lift and healthy appearance. The combination of essential oils such as Ylang Ylang and Cedar also gives the solid shampoo a wonderful mild spicy scent.


"Each Nature Bar soap and shampoo bar has a locally sourced rescued ingredient as its core ingredient. For example, we work together with local Amsterdam entrepreneurs on a circular economy. And together we combat waste. In this solid shampoo, Nature Bar processes the brewer's grains that are leftover from the brewery process of Brouwerij Troost, a local beer brewery in Amsterdam."

Beer is often brewed with malt and barley. Malt provides a lot of volume and barley strengthens hair and prevents hair breakage. The natural shampoo bar is therefore a top choice for thin and lifeless hair that could use some extra volume.


If you used to wash your hair with regular shampoo in the past, you may not be immediately satisfied with the natural alternative after the first wash. This is because your hair has become accustomed to silicones that are present in regular shampoos. Silicones put a layer over your hair, making it feel smooth and shiny, but at the same time, it closes your hair and has no chance to breathe. Natural hair soap washes this silicone from your hair and before it has completely disappeared your hair can feel greasy. Therefore, give your hair and scalp a chance to “kick-off” from regular shampoo for two weeks and ensure that it can regain its natural function. After this, your hair will look healthy, full and radiant! If you are still not convinced after two weeks, you can still use it as body soap because it contains many delicious and nourishing ingredients for the skin.

A great way to help you along is making your own ACV Hair Rinsewhich gently cleanses the scalp and conditions your hair. It removes build-up and impurities from the hair, increases softness and shine, and restores the natural pH balance of your scalp.


When you first use a natural shampoo bar, your hair may feel oily at first. Give it some time! Your scalp has to get used to the mild natural form of cleaning. After a number of washes, the PH value of your scalp and hair neutralises and you will notice that you get visible volume.

The use of a solid shampoo and a liquid shampoo from a bottle are not very different. Yet many people are unsure about it, so you can read in the article “using a shampoo bar” exactly how you can best do this.
