TLDR FPHL affects hair density and diameter, causing visible hair loss in older women.
Female pattern hair loss (FPHL) is a common condition that affects hair density and diameter, leading to visible hair loss in women. The prevalence of FPHL varies depending on diagnostic thresholds, but it is more common in older women and is associated with lower hair density. Hair diameter may affect the subjective impression of hair loss, and low hair density is not due to progressive diminution in hair follicle size. Measuring hair density and diameter can aid in diagnosing and monitoring FPHL in women. Further research is necessary to fully comprehend the underlying causes of this condition.
