Simple is a shampoo bar defined more by what’s not included. No potential irritants like natural fragrance, essential oils, colourants, proteins or vitamin E. Just simple gentle cleaning.

Designed for sensitive skin and hair, the Simple shampoo bar contains nourishing shea butter and calendula oil to leave your hair and scalp moisturized after you wash.

Most hair and skincare products contain allergens like formaldehyde-releasing preservatives, cocamidopropyl betaine, parabens, or sulfates. None of our shampoos include these ingredients. But in Simple we’ve gone further by removing other potential irritants, even natural ones like essential oils and plant proteins.

Note: While we don’t use any essential oils in this shampoo bar, we do make it using the same equipment as our regular shampoo bars. We cannot promise irritants aren’t present in trace amounts, so if you have a severe allergy or intolerance, the Simple shampoo bar isn’t for you.

Special Features

All information is for educational purposes only. We do not aim to diagnose, treat, cure, or prevent any disease or illness. You should consult a medical professional for advice should you have any hair or scalp conditions.

Lather the bar between your hands or rub directly onto your hair. A little goes a long way. Massage into your scalp, then rinse. thoroughly.

Store out of direct contact with water.


  • Some people notice they are going through their shampoo faster than they expect. If this happens to you, lather the shampoo bar in your hands, apply the foam to your hair, and massage the foam in. This way you can better control how much you are using.
  • If you have long hair, you don’t need to wash the entire length of your hair – shampoo is designed to clean your scalp. When you rinse out the foam, you will clean the lengths of your hair as well.
  • If you have thick hair, you might find it easier to wash your hair in sections.
  • nul shampoo bars have a creamy lather which is great for the “curly girl” method as they won’t strip your hair and scalp of its natural oils. This might take some getting used to but is much better for the health of your hair and scalp.
  • If you have oily hair or use a lot of styling products, wash twice for a deep clean. The second time you’ll notice much more foam.

    Dieser Bewertung wurde für eine frühere Version unseres Shampoos geschrieben
    Ich habe mehr als zehn Jahren lang mit Furunkeln und Kofphaut Ausschlägen gekämpft. Eine Therapie mit Roaccutan hat nicht nur nichts gebracht sondern auch Schäden (sehr trockene Augen, Lippen und Nase) zugefügt. Seitdem ich die Simple benutzte, sind die Furunkeln weg. Eure Produkte sind echt toll!

    The way my hair feels after using this shampoo for the first time is just brilliant. I am using brands with a sustainable approach/ vegan etc. since almost 15 years and tried many different solid shampoos so I feel I have a good sense of being able to compare. And I must say: this is a refreshingly simple but great no nonsense product I will keep using for sure. It does not produce too much foam but just enough to have that „my hair will be cleaned nicely“ feeling. After washing my hair was super easy to brush and once dried it felt healthy and robust (I have quite fine/ thin hair). So to sum it up: this shampoo will stay for good. And knowing it is produced just around the corner makes me feel even better. Bravo!

    Such a great shampoo! Really makes my hair super shiny and I love that it is sustainable and doesn’t have any of the regular „nonsense“ that you get in shampoos from supermarkets. I would highly recommend it!

    I was offered free samples in exchange for my honest review.
    Picking a shampoo is not easy for me as I have extremely sensitive skin. I tried many shampoo bars, but none really worked for me, they would make my scalp dry and generally irritate my skin.
    I have not given up on finding a good zero waste shampoo, so I was eager to try Nul Simple.
    Overall, I like it. The smell is subtle but nice. Having used it mostly daily for about 10 days, my sensitive scalp handles it well, with very minor irritation. This is a big win for me!! I also like the consistency: it does not crumble, which was the case with some of the other zero waste shampoo bars I tried containing ingredients like coconut oil. Thanks to the possibility to hang it in the shower, it dries well – another huge plus. On top of the quality of the shampoo, I also like the eco-friendly packaging!

    I got the simple shampoo bar and a sample of a conditioner for free. I was so happy to hear that I have the opportunity to test nul’s products and this is my honest opinion of the products. I have been wanting to test shampoo and conditioner bars for many years now, but it was always so hard to find suitable bars so I never bought one. Katie helped me to find the right bar and so far I have been really happy with the simple bar. My scalp is pretty oily due to a scalp medication, my hair is fine and slightly curly. To be honest I was a bit afraid that the bars would not clean my hair properly, or that the shampoo would be too strong. This was not the case with the simple bar and the conditioner. The shampoo bar cleans my hair and scalp very well, there was also no irritation or greasy look after the was. I was also really impressed with the conditioner bar, I really hope that you will start to sell this conditioner soon!

    Meine sehr dicken Haare haben sich noch nie so leicht und luftig angefühlt. Vorher neigten meine Haare zu Trockenheit. Seit ich den Shampoo Bar benutze, gehört das der Vergangenheit an. Ausserdem brauche ich keine Stylingprodukte mehr, um meine Haare zu bändigen.

  8. Guest Review

    Ich habe eigentlich eine juckende Kopfhaut und Schuppen und fettiges Haar. Seitdem ich das simple benutze, ist das Jucken weg und meine Haare sind mega weich. Auch die Schuppen sind weniger geworden. Ich bin total begeistert, denn meine Haare sind lockerleicht und nicht mehr so schwer.
