Product Information The Olaplex No 1 Bond Multiplier is a hair product that makes strands soft and shiny. This product works great for thin or damaged hair strands. Use the multiplier, too, if your hair has been affected by chemical treatments or environmental elements. After applying Olaplex No 1, dry, brittle strands take on a glossy appearance while weak hair slowly builds up its strength. Only a small amount is needed to treat a full head of hair which makes this product long lasting. Product Identifiers Brand Olaplex
