Welcome to Healthcaremagic.
Shampoos have propensity to show response based on the skin type and the hair type.Once adjusted need to be on the same brand.Well its bad to hear that the brand you had well suited to you is not available to in your locality.
Do try MINOXIDIL
5 % , applied to the scalp
every alternate day.This improves the blood supply to the scalp and help in growth of the hair and hence its health.
Do not try any new brand of shampoos when you have a serious problem of hair fall
Hope I answered your query.
Wish you good health.
