Hi, welcome to HCM.
with little history, it seems that you are having follicullitis .
It is an infection of hair follicle.
In your case it is relapsing.
Relapse may be due to poor nutrition,poor hygiene and poor immunity.
Blood tests may be done to rule out..DM,HIV
and other internal diseases.
Take bath with dettol
, the antiseptic , avoid soap bath.
Have good nutrition, take healthy diet.
Do not worry. Avoid stress
Proper antibiotics for long time may improve your disease.
Hope you got my answer.
