For those wit experience goin to dermatologist. Can i ask how they check ur scalp? Been researching in the internet n seems like there can be a few test done ie skin biopsy/ blood test for any nutrients deficiency. However reading the reviews seems like most dermatologist jz hv a glance at the hair and then can tell instantly whether it's mpb or wut.. Any good and honest dermatologist to recommend? Seems like there is bad review for every dermatologist .. Peningg

anyone been to dermatologist before where the doctor really check via blood test/scalp biopsy/ hair under microscope?
