The condition was first reported by Western travelers to Eastern Europe who saw it on the heads of local peasants. Therefore, the plica became associated with Polish territories, although the living conditions of peasants were pretty bad for most of Eastern Europe.
For a long time, plica polonica was surrounded by mystery. It was even considered to be the work of evil spirits: devils, strigoi, and witches, namely Polish witches. Those affected were cautioned not to cut it, as cutting the plait could supposedly result in blindness, hearing impairment, madness, bleedings and even violent convulsions. Actually, for quite a long time, even doctors weren’t sure if it was a disease, and were unaware of what caused it. Some believed it was a distinct disease entity, a neurotic condition, or a symptom of rheumatism, while others considered it an inherited disease.
Today, we know that the condition known as plica polonica is caused by the lack of proper hygiene, poor hair care, and the various diseases caused by all of that. Be it in Poland or anywhere else.
