androgenetic alopecia hair follicles scalp hypodermis magnetic resonance imaging AGA MRI

TLDR MRI reveals thinner scalps and smaller hair follicles in people with androgenetic alopecia.

This study used MRI to analyze the anatomical changes in the scalp and hair follicles in androgenetic alopecia (AGA). The study found significant differences in the thickness of the scalp and the size of hair follicles between individuals with AGA and those without. The AGA group had a thinner hypodermis and entire scalp, as well as shallower hair follicles. MRI can be a promising new method for quantitative and objective analyses of AGA.
