Garrett Morgan's discovery of his hair-straightening product was an accidental byproduct of his work on sewing machines. In 1907, while experimenting with a chemical solution to reduce friction and prevent scorching when sewing machines' needles moved rapidly, he noticed the solution also straightened fabric fibers. He later realized this chemical compound was safe for human hair and could be used to straighten it. This led him to found the G.A. Morgan Hair Refining Company in 1913 to market the product.1
