Talk to Dermatologist on Hairloss (bald Patches) From Scalp And Other Parts Of Body

by the start of this year I developed bald patches on my scalp... like really big patches with smooth skin showing and before their formation i faced severe itching on those areas.... I consulted a dermatologist and used a medicated lotion and oil for recovery... after sometime my hair grew on those areas and I thought I'm recovering... but from last 1 or 2 months I am facing severe itching again on some other sides of my scalp and I've noticed small bald patches on so many sides of my head with severe hairloss... Moreover I'm noticing this itching on private parts of my body now and I've noticed loss of hair from those parts as well, they are not completely bald but I can see my skin now...
