Since 2019, Hello Klean’s shower filters have set out to solve the common woes of hard water, from brittle strands to the dulling of bright, beautiful hair hues. Seven years on, its latest device – the shower head+ – aims to take things one step further than simply filtering your water, combining the brand’s three-stage filtration system with smart tracking technology that monitors everything from shower temperature to filter lifespan.
Having previously tested the shower head 2.0, I spent 14 months comparing the two models to see whether the added connectivity actually makes a difference. While the right shampoos and conditioners can help improve the look and feel of your hair, tackling the mineral build-up that comes from hard water at the source can be a more effective long-term solution.
