The result? The Gloss Complex with [Glycolic Acid] has a lightweight smoothing effect on hair as it perfectly smoothens the fibre's surface. Hair is shiny, smooth & soft to touch. 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. How to use? After using the Glycolic Gloss Shampoo apply from lengths to tips. Leave on for three minutes, then rinse. For maximum shine, follow with the Glycolic Gloss Rinse-Off 5 Minute Lamination Treatment and Leave-In Serum. Suitable for all: Effective on all hair types, ranging from straight, wavy, curly, and coily. * 82% of women agree.
