If your hair feels straw-like after washing, won’t lather properly or looks dull no matter what you use, hard water is a likely culprit. Many Indian cities have water high in calcium and magnesium, which leaves a film on hair and scalp.
Does hard water cause hair fall?
The evidence says it mainly affects the feel of hair: it becomes rougher and more tangle-prone, and breaks more when brushed. Genuine hair fall — clumps on the pillow or a widening parting — usually has other causes, such as stress, iron or thyroid issues, or genetics, and is worth discussing with a doctor.
What helps
Clarify once a week
Use a chelating or clarifying shampoo (look for EDTA or citric acid on the label) to lift mineral build-up. Follow with a rich conditioner.
Condition every time
Apply from mid-lengths to ends and detangle with a wide-tooth comb while it is in.
Try an acidic rinse
A diluted apple cider vinegar rinse (1 tablespoon in a mug of water) can smooth the cuticle. Keep it off irritated scalp.
Consider a shower filter
Filters vary a lot in what they remove. If you try one, choose one that states it reduces calcium and magnesium, and replace the cartridge on time.
What is mostly marketing
“Hard water” shampoos without a chelating ingredient are just shampoos. And no product can undo mineral build-up if you never clarify — consistency beats the price tag.
