My scalp is prone to dandruff and its oily and I have started loosing my hair a lot and its uncountable. Now my scalp has become see thru with very thin hair (genetics). I use to suffer from gastric issues continuously and I am unable to treat it. I use head and shoulder shampoo which just dries my scalp a lot and causes further hair loss. Can you say me what to do and what mild anti dandruff shampoo can I use though?
