Hard water is associated with mineral deposits and can make soap harder to rinse away. Some people notice dryness or tightness, but skin symptoms have many possible causes and are not proof of a water problem.
What may be happening?
Calcium and magnesium can react with soap, leaving residue on skin or shower surfaces. Hot water, long showers, fragranced products, eczema and local plumbing can also contribute to irritation.
Start with simple changes
Use lukewarm water, rinse thoroughly, pat skin dry and choose a gentle, fragrance-free cleanser or moisturiser if appropriate. Change one variable at a time so you can tell what helps.
When should you investigate water?
If the issue affects the whole household or coincides with a change in supply, check local water information and inspect the showerhead. Persistent or severe symptoms should be discussed with a qualified healthcare professional.
