Frictional Hair Loss in Iraqi Patients

Abstract

A total of 50 Iraqi male patients with frictional hair loss were studied. Their ages ranged from 27-55 years with a mean +/- SD of 40.60 +/- 7.82 years. The age of onset ranged from 26-50 years with a mean +/- SD of 38 +/- 7.3 years. The duration of disease was 1-5 years, mean +/- SD 2.2 +/- 1.3. Middle age was the most common age group affected. Patterns of hair loss were as follows; bilateral thighs & legs 13 (26%), bilateral thighs alone in 9 patients (18%), bilateral shins & calves (legs) in 4 patients (8%), abdomen alone in 8 patients (16%), thigh and abdomen 4 (8%) patients, legs & abdomen 4 (8%) patients, and all sites in 12 patients (24%). The pattern of patchy hair loss showed some etiological preference. It was found to be due to continuous pressure from socks, trousers and bed. Skin biopsies from five patients showed apparently normal histology. Twenty-six (52%) of the cases were healthy. There were no important medical or dermatological associations, such as alopecia areata or peripheral neuropathy in any patient although unrelated medical conditions were seen in 24 (48%). To the best of our knowledge, this type of patchy hair loss has attracted very little attention in the past, and the literature appeared to be deficient in references to this problem.

Frictional alopecia of the distal legs: case series and review

“…Alopecia is categorized as scarring and non-scarring. Frictional alopecia is a subtype of non-scarring traumatic alopecia caused by repetitive friction on hair-bearing areas of skin [1]. In this report, we describe a series of five men who presented with frictioninduced alopecia of their lower extremities in a distribution corresponding to locations covered by either socks, footwear, or both.…”

Frictional (Sock) alopecia of the legs: Trichoscopy as an aid

“…Frictional alopecia is a type of acquired nonscarring alopecia caused due to repetitive friction on the hair-bearing sites. [ 1 ] Frictional alopecia on lower extremities can occur due to socks and/or footwear. The typical site of involvement gives a clue to the diagnosis, but it needs to be differentiated from other causes of alopecia.…”
