The Bond Maintenance No° 5 by OLAPLEX is a revolutionary, USA-based product formula that repairs, strengthens and hydrates all hair types. Hairdressers can confirm that chemical applications such as bleaching or colouring, as well as the use of heat from blow-dryers, flat irons or UV rays, strain the hair. This causes damage to the structure of the hair, loss of shine and smoothness ultimately leading hair to becoming brittle. This is now a thing of the past: The OLAPLEX 8-fold patented active ingredient enables you to repair damaged hair sustainably. 557
