Pseudo Alopecia Areata Caused by Skull-Caps with Metal Pin Fasteners Used by Orthodox Jews in Israel

The study investigated a variant of Alopecia Areata (AA) called Pseudo Alopecia Areata, caused by the use of skull-caps with metal pin fasteners among Orthodox Jews in Israel. Conducted on 37 patients, the study explored non-pharmacological treatment options (NPT) by altering the pin and cupola configurations. Results showed that adding a second pin led to additional lesions in 33.3% of patients, while replacing the original pin with a different type on a larger cupola resulted in immediate improvement for 58.8% of patients. The study concluded that conservative pharmacological treatments were ineffective, but modifying the pin and cupola successfully reduced lesions.
