K18 is a brand that never does things by halves, and absolutely never launches 'that'll do' products to fill a gap in a marketing calendar. Wouldn't dream of it.
So after the original Molecular Repair Mask - a genuine "game changer" as my K18 Review breathlessly attests - and a dry shampoo that works unlike any other (spoiler: it's wet) as of this week, we get TripleBright Oxidation Defence, the brand's stab at making the best purple shampoo on the market.
