Collapse of human scalp microbiome network in dandruff and seborrhoeic dermatitis

We investigate the relationship between scalp microbiota and dandruff/seborrhoeic dermatitis (D/SD), an unpleasant scalp disorder common in human populations. Bacterial and fungal community analyses on scalp of 102 Korean were performed by next‐generation sequencing. Overall scalp microbiome composition significantly differed between normal and disease groups, and especially co‐occurrence network of dominant members was breakdown in disease groups. These findings will provide novel insights into shifts of microbial community relevant to D/SD.
