Goldwell Dualsenses Bond Pro Fortifying Conditioner 200ml is a conditioner for weak and fragile hair. It contains an inter-amino-bond builder, which ensures that amino acids and peptides penetrate deep into the hair cortex and target damaged areas of the hair. Peptides are stored in the inner cortex of the hair through ionic and hydrogen bonds, resulting in stronger and more durable hair fibers. The innovative microPROtec technology offers a fast and even distribution that ensures optimal care and refreshment of the hair without weighing it down. The conditioner protects against mechanical damage such as combing or brushing and ensures that the hair does not break. Hair becomes stronger and takes on a healthy, shiny look. How to use: 1. Apply an appropriate amount of conditioner to wet hair. 2. Massage in and let soak in. 3. Finally, rinse completely.
