« SLS is commonly used in shampoos, hair conditioners, hand wash and shower gels.
It is a very harsh detergent used to make the products foam when used.
SLS can cause irritation of the eyes, skin rashes and flaking skin, and possibly permanent damage to the eyes, especially in children.
Research was conducted in the Department of Dermatology at the School of Medicine, University of California on the ability of SLS to penetrate into the skin and underlying tissues. The research found that Sodium lauryl sulphate penetrated the skin directly to a depth of about 5-6 mm below the applied site. Epidermal levels of the compound after application of 1% aqueous solution for 24 hours were above threshold levels known to evoke skin irritation responses. Deeper underlying tissues may also have been exposed to high levels of the compound. SLS reacts with other chemicals found in shampoos and cleansers to produce nitrates, which can enter the blood stream easily. »

My point of view: The more foam equal the more harm!
A good alternative: Rassul, a special type of clay used since ancient times & still used to clean skin & hair in Morocco. It absorbs dirt from the skin, hair & scalp without any foam. It is an excellent cleansing alternative for sensitive skin or those who cannot use detergents.
