Olaplex 

The first ever revolutionary hair repair treatment of its kind. 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. Olaplex links broken bonds in the hair before, during and after chemical services.

A patented active ingredient that works on a molecular level to seek out broken bonds in the hair that are caused by chemical, thermal, and mechanical damage. You can use Olaplex to restore compromised hair, or add it to another service to provide the ultimate breakage insurance.
