Hi drs.my father had dandruff and hairfall for about 5 yrs.he used some cosmetics and medications but all failed.is there any solution?

Dandruff Solution: Unfortunately, "herbal shampoo" doesn't really qualify as medication. Your father should seek an appointment with a dermatologist to control the dandruff (there are many possible causes), then seek advice from an abhrs-certified hair restoration physician to address the hair loss. Ask for sequential cross sectional bundle trichometry measurements to track the resolution of the hair loss.
