Frictional Alopecia of the Distal Legs: Case Series and Review

The study reviewed cases of frictional alopecia of the distal legs, focusing on 5 patients who experienced hair loss on their lower legs due to friction from socks and footwear. This type of alopecia was identified as a non-scarring condition that often went unnoticed until a physical examination. Despite removing the source of friction, the condition could persist for many years. The research suggested that the incidence of this condition might have been higher than previously reported in the literature.
