OLAPLEX No.2 BOND PERFECTOR is a crucial step in the Olaplex system. It’s not an option – it’s a must after every Olaplex treatment. While No.1 helps protect hair during coloring, lightening, or relaxing, it can’t do it all alone. No.2 steps in to complete the process by reconnecting broken bonds, ensuring a visible improvement in your hair’s health and appearance. It’s not a conditioner or activator – it’s specifically designed to work with No.1 to repair and strengthen your hair. With the same active ingredients, No.2 tackles even more bonds, leaving your hair stronger and more resilient, without interference from coloring or lightening agents.
