REVIEW: Nature Box Avocado Shampoo ⭐️ For a while now, I have been working on the Curly Girl method, avoiding silicones, sulfates, mineral oils, wax and drying alcohols in your hair routine. This shampoo meets the requirements for this method, which is certainly a plus. BUT... I notice this product irritates my scalp and that I get itchy from this shampoo. The shampoo contains Sodium C14-16 Olefin Sulfonate (no this is not sulfate), this substance can cause dehydration and irritation. This ingredient is second on the ingredients list, which makes it possible that this is really too heavy for my scalp. In addition, there is Cocomidopropyl Betaine in this shampoo, an ingredient that many people are allergic to and eczema. This is the third ingredient on the ingredient list. Unfortunately for me really not a suitable shampoo. It's a shame because there are also many properties on this product that do your hair well. Cold-pressed avocado oil, which contains valuable vitamins and antioxidants and a vegan formula attracted me to buy this product. (Product requested on weareeves)
