18th Century warning on Petroleum Hair-Washes…”The special danger arising in their use is that the liquid may be ignited by a light or fire some distance away….this has been known to occur even when the liquid was over 40ft distant from the point of ignition…..the use of petroleum spirit hair-washes is, therefore, so exceptionally dangerous that it is hoped hairdressers and others will do their utmost to discourage the practice”
