If you struggle to find a 100% clean product, you can also go for a product with low concentration of blacklist ingredients (at the end of the formulation). Especially when it comes to the reset shampoo, it will be fine for most people to tolerate a low concentration of these ingredients, because this product is meant to be used 1-2 times a month maximum. As for everything, quantity is the real issue. So a low concentration of blacklist ingredients in a product we rarely use is actually ok. Only extra sensitive people may have to really find a perfectly clean product. ​Also, many of our students have shared in the past the clean sulfate shampoos they found, you should be able to find the posts my typing 'sulfate shampoo' or 'blacklist free' in the community search bar.
