Sonographic Comparison of Subcutaneous Fat Layer Thickness in the Scalp Area in Patients with Androgenetic Alopecia Compared to Healthy Individuals: Cross-Sectional

This cross-sectional case-control study compared subcutaneous fat layer thickness in the scalp of 30 individuals with androgenetic alopecia (AGA) to 30 healthy controls. The study found that individuals with AGA had significantly thicker subcutaneous fat in the frontal scalp region compared to healthy individuals, with men showing a greater increase than women. The occipital region's fat layer thickness was similar between patients and controls. Age influenced fat layer thickness, with older individuals showing greater thickness in both regions. These findings suggest that subcutaneous fat layer thickness plays a role in AGA and varies by scalp region and gender, indicating potential for targeted treatments.
