Myself phani kumar, male, 31yrs. Previously I had few grey hair (white hair) on my head and gradually more than 50% black hair converted into white hair on head and few white hair started coming on beard as well. In our family (father side) no such problem happened I.e getting white hair in 30's age. Previously I worked in Shipping (sea port) operations division for coal handling (bulk coal import/export through ships) and worked something like 24/7 job whenever ships come have to attend it may be day/night/midnight/early hrs like ways worked for 2yrs continusly. This is the entire situation related to my work and health conditions. Previously I took gout treatment 1month before. Please suggest the relevant tests and further treatments.
