Olaplex was developed by Dr. Eric Pressly and Craig Hawker, two of the world's leading chemists. This dream team invented a single ingredient chemistry, that is free of silicones and oils and has break through technology that eliminates a large percentage of damage during the colouring process. Olaplex links broken bonds in the hair before, during and after chemical services and this fabulous step 3 take home treatment is perfect for rebuilding damaged hair in between visits to the salon.
