I Have Severe Dandruff /dry Scalp . I Stay In
Water filter needed
Hello and welcome to Ask A Doctor service.
You can always test the borewell water with TDS meter. RO system should be functional. Recommended TDS for drinking water is less than 50 PPM in people with dry skin.
Coconut oil may work. Vaseline may work especially after washing skin. Avoid long showers.
If allergy is being triggered then chemicals for skin care need to be avoided. Natural ways need to be started for skincare like using besan, sandal or natural soaps like everyuth naturals, XXXXXXX XXXXXXX Tattva for skin care
What medicines have you tried? Using stronger medicines like urea or anti-dandruff shampoos containing ketoconazole etc are to be avoided in allergic skin.
Hope this helps. Let me know if I can assist you further.
Most of the above applies to your health as well.
RO System (keeping the TDS low) is good enough. It has started coming with various add-on like copper zinc, minerals etc, which I think are not really needed. We can get enough minerals and vitamins from well-balanced nutritious diet.
