We do not use sodium laureth sulphate (SLES), or sodium lauryl sulphate (SLS) in any of our products. Whilst our conditioners, hair masks and haircare bars are sulphate-free, we do use ammonium lauryl sulphate (ALS) in our shampoos, body washes and hand washes. ALS is considered a safe and effective cleansing agent and is biodegradable. Virtually 100% of this base is immediately removed from the skin or hair by the simple act of rinsing with water.
