In 1907, America was at war against tuberculosis, which killed hundreds of people from the 1880s to the 1950s. To complement their pale complexions, survivors opted for masses of ringlets, thanks to the invention of the waving iron in the 1870s. Hair coloring was frowned upon, but the brave went for it anyway, using herbs, rust, and other concoctions. To promote hair growth, petroleum jelly, castor oil, and gallic acid were also part of the beauty arsenal.
