K18 Molecular Repair Hair Oil 30ml Review: Smooth Finish

K18 Molecular Repair Hair Oil 30ml earns its place in Great Finds by feeling genuinely useful rather than showy: a silky, lightweight hair oil with a clean, salon-like scent that smooths dry ends without leaving that coated feel. It suits heat-styled, coloured or frizz-prone hair, especially before a blow-dry or as a last touch on mid-lengths. The only caveat is restraint; on very fine hair, too much can flatten the finish. Available in the United Kingdom, it feels considered and practical.
