Ultra-nourishing yet completely weightless, the innovative No. 7 Bonding Oil restores and renews your hair without coating it in a greasy film. Expect silky smooth lengths that shines. Formulated to rebuild the damaged disulphide bonds in your hair, the star ingredient is bis-aminopropyl diglycol dimaleate – sounds science-y but 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°!), this oh-so dreamy oil sinks into stressed-out hair to make it instantly more manageable.
