Elvive Glycolic + Gloss Hair Care System transforms dull, porous hair, giving strands an instant high shine and next-level gloss. Inspired by skincare, the formulas are infused with Glycolic Acid to help hair reflect maximum light. The Shine Boosting Shampoo gently cleanses and instantly smoothes, while the Shine Boosting Conditioner instantly detangles and adds shine. The High-Shine Leave-In Serum, with a 4% Glycolic Acid Complex, makes hair 14x smoother for an extra boost of shine and can be used on both damp and dry hair. For best use, use the complete Glycolic + Gloss system. Apply Shine Boosting Shampoo to wet hair, massage and lather, rinse. After Shampooing, apply Shine Boosting Conditioner to lengths. Leave on for 1 minute and rinse. Follow with a small amount of High-Shine Leave-In Serum, applying evenly to damp or dry hair, focusing on the lengths and ends. Apply more product as needed. Do not rinse. Our hair care system is ideal for everyday shine, big nights out, or special occasions when you want glossy, polished hair that stands out.
