The 5-Minute Glycolic Gloss Lamination Treatment perfectly seals the cuticles to smooth their surface, giving the hair shine. Healthy-looking hair is shiny because its smooth surface perfectly reflects light. On the other hand, damaged hair has ruined cuticles and the fiber is rough, porous, and dull, unable to reflect light. Our first at-home Gloss Treatment, powered by Glycolic Acid, repairs the fiber from within, intensely improving hair quality and sealing the cuticles for lasting shine. Quantity: 200ml.
