We do not use sodium laureth sulphate (SLES), or sodium lauryl sulphate (SLS) in any of our products. We do use ammonium laureth sulphate (ALES) in our shampoos, shower gels and hand washes. ALES is considered to be 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. Our hair conditioners do not contain any sulphates.
