There's a new OLAPLEX product in town, as you may have heard. The OLAPLEX Nº.4C Bond MaintenanceTM Clarifying Shampoo is now available! Nº.4C is an advanced clarifying shampoo that removes all types of damaging impurities without stripping the hair, paving the way for healthier hair. Clean hair is a science! Nº.4C uses patented Bond Maintenance technology to rebuild hair's bonds and make it healthier than before, all while doing all of the above. In addition to removing oils, product buildup, minerals, and chlorine, OLAPLEX also eliminates heavy metals and pollution, setting it apart from other clarifying shampoos on the market. In the process, it mends broken bonds—a function for which only OLAPLEX has received a U.S. patent. How then does it operate? Every week, use the OLAPLEX N.4C Bond MaintenanceTM Clarifying Shampoo.
