The short explanation
Hard water, which has more minerals such as calcium and magnesium, can leave hair feeling rough, dry and more prone to breakage. This may make hair look thinner and break more when combing. But hard water is not usually a direct cause of hair falling from the roots. Moving to a new city often comes with other changes that can trigger hair shedding: stress, irregular meals, less protein, poor sleep, illness such as a fever after the move, or changes in your hair care routine. These can cause a temporary increase in hair fall that shows up a couple of months later. If the shedding continues, a doctor can check for iron deficiency, thyroid problems or other causes.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A mild, gentle shampoo, conditioner and avoiding very hot water may help with dryness and breakage from hard water.
- Some people use a filter on the shower head, though evidence that this reduces hair fall is limited.
- Hair falling from the roots with a white bulb at the end is shedding, while short broken pieces suggest breakage.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you why your hair is falling. A doctor can examine your scalp and check your blood tests.
