Laser-capture microdissection (LCM) enables the study of the hair follicle (HF) microbiome in relation to hair health and disease with high spatial resolution. It allows the precise excision of specific HF regions, each containing a unique and conserved microbiome, from full-length HFs encompassing all relevant HF compartments. With LCM, cross-contamination with microbiota from neighboring regions is minimized. Coupled with 16S rRNA gene or metagenomic shotgun sequencing, LCM offers great potential to assess region-specific microbiome changes, particularly in HF-associated disorders.

With LCM, cross-contamination with microbiota from neighboring regions is minimized. Coupled with 16S rRNA gene or metagenomic shotgun sequencing, LCM offers great potential to assess region-specific microbiome changes, particularly in HF-associated disorders.
