HLCC Scripts Shampoo has been scientifically formulated without DEA/MEA (DEA has cancer questions)LINK and/or Sodium or Aluminum laurel sulfate (SLS) derivatives, as part of the active ingredients, unlike almost all other commonly used hair and scalp cleansing products. In light of recent research regarding the safety of DEA and SLS, we offer this healthy alternative - a blend of mild, non-irritating cleansing agents with water-soluble polymers that provides moisture and added shine to hair, but without harsh and potentially damaging chemical additives. Because this shampoo is so gentle, it can be used every day. Its unique formula effectively removes undesirable scalp residue and build-up while simultaneously providing strength, moisture and shine to the hair.
