TLDR The new system helps detect and track early female hair loss better.

The study introduced a new grading system for early female pattern hair loss (FPHL) based on changes in hair surface reflection patterns observed in global photographs (GPs). A retrospective review of 114 patients classified their GPs into five grades, finding that higher GP grades correlated with increased hair diameter diversity and FPHL-severity index (FPHL-SI) values. The concordance rate of grading between the author and volunteers was 57%, while the concordance rate for course evaluation was 97%. The new classification system proved effective in finely classifying early FPHL and evaluating treatment progress, aiding in early detection and treatment assessment.

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
