hello there.
hairfall and premature greying can be due to a lot of reasons which include, dietary deficiencies, autoimmune disorders, hormonal disturbances, stress, scalp infections etc.
to come to a exact diagnosis of what is causing your problem, you will have to contact a dermatologist and visit him and get examined by him .
he will do the needful. because we cannot pinpoint any particular thing without seeing.
