Comprehensive, weightless care Redken's Acidic Bonding Concentrate Lightweight Liquid Conditioner is a spray conditioner with a liquid consistency that cares for fine hair that is weak and stressed, repairing it from within. Fine, weak hair fibres, that are stressed as a result of chemical treatments, environmental influences or heat styling, need extra care to restore resilience and a healthy appearance. The Acidic Bonding Concentrate Lightweight Liquid Conditioner is enriched with a bonding care complex and citric acid. Fine hair is not weighed down in any way and detangling the hair is child's play. Hair appears fuller and takes on a freshly washed appearance for up to 2 days because the process of oil buildup is slowed down. Application: For best results, use the conditioner after cleansing the hair with the Acidic Bonding Concentrate Shampoo. Depending on the length of the hair, spray several pumps onto the lengths and ends of the hair. Leave it on for 1 - 2 minutes then rinse thoroughly. It is recommended to follow up with the Acidic Perfecting Concentrate Leave-In Treatment.
