Numerous studies have proven the surprising extent to which your hair can affect your mood and social status. Caring for your mane is a part of good hygiene and helps make a good impression on others, which is why most people carry a comb with them wherever they go.
In the late 1800s, tortoiseshell combs became a trend, however, most weren’t really made from tortoiseshell. Instead, they were made using a highly combustible and very unstable celluloid compound. The combs didn’t have to be exposed to fire to explode. Simply get one close to a heat source and you were at risk of seeing it explode.
