Ultra-nourishing yet completely weightless, the innovative Olaplex No 7 Bonding Oil restores and renews your hair without coating it in a greasy film. Formulated to rebuild the damaged disulphide bonds in your hair, it works to strengthen and repair damage post-colouring, bleaching or heat styling (and it even works wonders on ‘virgin’ hair!) Perfect as a conditioning treatment or a styling step (it protects against heat up to 450°!), Olaplex No 7 Bonding Oil sinks into stressed-out tresses to make them instantly more manageable – smoothing frizz and taming flyaways in its wake.
