Hi, Welcome to Chat Doctor forum.  It appears that you might be having deficiency of vitamin A, hemoglobin, and proteins etc. which are most important for hair growth.  I advise you to consult a dermatologist, for diagnosis and treatment.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to recover the deficiencies.  Make a habit of shaving the beard and mustache regularly on alternate days.  Wishing for a quick and complete recovery. Thank you.
