After living in London for 33 years, a beauty editor tested eight shower filters to combat hard water, which affects 60% of UK water, according to Scaleguard. The filters were evaluated for efficacy on hair, skin, and limescale buildup.
Why Hard Water Matters
Hard water contains over 200mg of calcium carbonate per litre in many areas, leading to limescale on fixtures and potential damage to hair and skin. Anabel Kingsley, Lead Trichologist at Philip Kingsley, notes that unfiltered water can carry heavy metals and minerals that harm scalp and hair health, contributing to conditions like dandruff, hair loss, and breakouts.
How the Filters Were Tested
Each filter was used for several weeks, monitoring changes in hair texture, skin condition, and limescale buildup. Installation ease, water pressure, and design were also assessed.
