female pattern hair loss FPHL hair density anagen hair ratio digital image analysis visual counting

TLDR Turkish women with female pattern hair loss have lower hair density, and visual counting is more effective than digital image analysis for detecting this.

In 2007, a study was conducted to quantify hair characteristics in Turkish women with female pattern hair loss (FPHL) and compare them with healthy volunteers. The study involved 39 patients with FPHL and 31 healthy volunteers. The results showed that the hair density and anagen hair ratio of the patients were significantly lower than those of the controls. The study also compared visual counting and digital image analysis methods for assessing hair density. It was found that digital image analysis underestimated hair density, especially in cases with higher hair density. Therefore, the study concluded that while diminished hair density is a key sign in diagnosing hair loss, digital image analysis may not be as effective as visual counting in detecting hair density.

in Research 692 upvotes 4 months 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.
