Abstract

BACKGROUND AND AIM: Hair straighteners have become increasingly common household appliances. The purpose of this study was to investigate the temperatures reached by the exposed plates of hair straighteners when switched on, and the length of time taken to cool to a safe temperature after switching off. We also present the case of a child with deep dermal burns caused by a hair straightener, highlighting its potential danger when left unattended. METHODS: Eight different hair straighteners were tested using a calibrated thermometer. Maximum temperature reached and length of time taken to cool to 40 degrees C were recorded three times for each straightener. RESULTS: Among the eight straighteners tested, the size of the plates varied between 22.5 and 53.9cm(2). Plate material was ceramic in all but one case. Average maximum temperature was 163 degrees C (122-210 degrees C). Mean time taken to cool to 40 degrees C from switch-off was 26min (18-44min). None of the devices tested could be locked closed. DISCUSSION AND CONCLUSION: Hair straighteners present a significant risk of burn when left unattended, both while switched on and for up to 44min after turning off. We offer some recommendations to improve safety.
