What makes it effective? Shiny hair is healthy-looking hair because its smooth surface perfectly reflects light. Hair damage disrupts cuticles, making fibres rough, porous, and dull unable to reflect light. Glycolic Gloss Sulphate-Free Shampoo is powered with Glycolic Acid which has a small molecular weight able to penetrate the hair & inject it with care. The Glycolic Gloss Complex contains conditioning agents to seal cuticles with a lasting shine glaze. Hair is shinier & smoother than ever before.
