The first hair straightener was invented by Ian Gutgold using harsh chemicals in lotions applied to the hair and scalp. However, these preparations often led to scorched scalps and damaged hair.


Simon E. Monroe patented a hair straightener in 1906 that was comprised of metallic teeth that are combed through the hair, while in 1909 Issac K. Shero patented a hair straightener comprised of two flat irons that are heated and pressed together.


Years later, Sharrell invented heated metal hair-care implements, such as hot combs. The hot metal straightener slid easily through the hair, causing less damage and dryness than previously-used techniques. Later, ceramic and electrical straighteners were introduced, allowing for adjustment of heat settings and straightener size.Who invented the first hair straightener/iron?
