Hello Panda,
We would like to bring to your notice that the ingredient used in Coconut Milk & Peptides Shampoo is SLES. SLES (Sodium Laureth Sulphate) is NOT the same as SLS. SLES unfortunately shares a very similar name with SLS, and there is very little else that's similar to SLS. We repeat that we do NOT use SLS in our products. We invite you to read our blog post on the topic: https://plumgoodness.com/blogs/ingredients/13030321-5-min-fundas-sls-vs-sles
We rely on internationally recognized studies on the safety of ingredients before accepting them, and that holds for SLES, too. Do reach us if you need more information about the safety of ingredients used in our products. There is a lot of information floating on the internet about ingredients, but we try to rely on scientific, international studies that can stand up to scrutiny.
If there's anything else we can help with, please do not hesitate to let us know.
Love,
Plum People
