Smartbond is L’Oréal Professionnel’s ultimate bond strengthening service, added to your colour services in salon to minimise any potential damage & protect your hair. The service is designed to protect the bonds deep within the hair & strengthen them during technical processes, such as lightening and colouring, resulting in hair that is stronger, feels touchably softer, and looks shinier. This treatment can be used on its own which takes thirty minutes or within your colour treatment which needs no additional time.
