L'Oréal Paris Elvive Glycolic Gloss Leave-In Serum for Dull Hair 150ml

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 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.

Usage:
Use as a finishing touch in the Glycolic Gloss routine for intense smoothness and ultimate shine. Rub two drops between the palms of your hands. Apply evenly through the lengths and ends of wet or dry hair.
