The Olaplex No. 7 Bonding Oil is a highly concentrated, weightless styling oil formulated to dramatically increase shine, softness, and color vibrancy. This innovative oil repairs and protects hair from UV and heat damage up to 450°F (232°C). It works by actively rebuilding broken bonds within the hair structure, leading to stronger, healthier strands. Ideal for all hair types, this product minimizes frizz and flyaways while providing a polished, finished look without weighing the hair down. Use a small amount as a finishing product or mix with other treatments for added benefits.
