A conditioning treatment by Philip Kingsley, the Swimcap Water-Resistant Mask protects the hair from the damaging effects of chlorinated and salt water, while UV absorbers defend from discolouration caused by the sun. Originally developed for US Olympic Synchronised Swimming Team, the formula is now used by swimmers and as a summer saviour, working to nourish and care for all hair types, including coloured and chemically treated. Fortified with hydrolysed elastin, the hair mask encourages visible strength and body, alongside helping to minimise the look of breakage and damage by plumping the fibres with lightweight moisture. Castor and olive oil lend long-lasting hydration, supporting a silky, high-shine finish that’s soft to the touch. Apply before sunbathing or swimming to damp hair for best results.
