Olaplex does not interfere with colour processing. It works independently to reform broken bonds that are not reforming properly with peroxide. It's simple to use and completely safe. New chemistry... New superpowers. Olaplex is a single active ingredient invented by Dr. Eric Pressly, PHD in materials, and Dr. Craig Hawker, PHD in Chemistry. Go Blonder. Push the envelope further without compromising the integrity of hair.
