female pattern hair loss FPHL Sinclair scale hair loss centroparietal region

TLDR New scale reliably assesses male hair loss with female pattern.

The paper presents a modified Sinclair scale for assessing female pattern hair loss (FPHL) in men, which includes five grades of severity based on the stage of hair loss in the centroparietal region. The scale was developed and validated, and can be used as a tool for assessing and monitoring hair loss in men with female pattern hair loss. The modified Sinclair scale was found to be reliable and valid for assessing FPHL in men.

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.
