Liquid Crystal unlike most other shampoos is completely free from Sodium Laurel Sulphate (SLS).
SLS is an eye irritant, it denatures (skin and hair is made up of protein). In short  SLS can damage the outer layer of skin, causing dryness, roughness, scaliness, fissuring, loss of flexibility and can reduce the barrier function of normal healthy skin.
Crystal Creme is just about the most effective conditioner there is. Excellent for necessary re-hydration of bleached or chemically treated hair. Brilliant, deep moisturizing chemo-prophylactic and anti-bacterial properties condition your hair like you condition your skin.
Like all Sircuit products both these products are super concentrated...a little goes a long way.
