Love your hair gel? How very ancient Egyptian of you! That's right: researchers have discovered that ancient Egyptians use hair products in life and in death.
Microscopy using light and electrons revealed that nine of the mummies had hair coated in a mysterious fat-like substance. The researchers used gas chromatography–mass spectrometry to separate out the different molecules in the samples, and found that the coating contained biological long-chain fatty acids including palmitic acid and stearic acid. The results are published in the Journal of Archaeological Science1.
McCreesh thinks that the fatty coating is a styling product that was used to set hair in place. It was found on both natural and artificial mummies, so she believes that it was a beauty product during life as well as a key part of the mummification process.
