Background of Model of in vitro human scalp microbiota

•    Based on 454 sequencing of the scalp microbiome, the two most abundant bacterial genera found on the scalp surface are Staphylococcus and Cutibacterium, while Malassezia is the main fungal inhabitant (Grimshaw et al., 2019).
•    The human scalp hosts an unusually low diversity microbiota dominated by three species: S. epidermidis, C. acnes and M. restricta.
