If your hair feels dry or rough, the best shower filter could be the missing link in your haircare routine, proving even more effective than a hair mask or bond repair treatment. Around 60 per cent of the UK has hard water, and while you might associate it with cloudy glasses and limescale-coated kettles, its mineral by-products can also wreak havoc on your scalp and strands.
“Hard water contains high levels of dissolved minerals, primarily calcium and magnesium – and these minerals can have a significant impact on both skin and hair health,” explains Dr Anjali Mahto, consultant dermatologist and founder of Self London.
