Brief Answer:
Seems to be altered normal flora of scalp

Detailed Answer:
Hello and welcome to Ask A Doctor service.

I have reviewed your query and here is my advice.

It seems that your scalp's flora got altered and medicines are making it worse.

Now the grey hair cannot be reversed to black hair. But we can save the remaining hair by taking our precautions. Avoid unnecessary medicines and medicated oils, shampoos etc.

Seasonal loss of hair is usually temporary and hair grow back.
I will suggest that you get tested for nutritional deficiency. Get blood test done - complete blood count, serum iron, folic acid, B12, calcium and vitamin D levels. After taking these tests, take the supplements for any deficiency present.

Seasonal skin removal is normal. You can help by drinking cleaner water from RO system. Also take citrus fruits and Limcee tablets.

Hope this helps. Let me know if I can assist you further.
