Going Brunette
Hair dye was around for much longer than one would think. Women would soak roots and nuts in hot water and then leave their hair in it for hours to achieve a darker shade of brown. This was particularly easy for people in the middle ages to maintain because nobody showered!
Being Blonde
An extremely important female trend of victorian times was the dyeing of blonde hair. People believed that angels possessed blond hair, and people who were blonde were considered closer to God. So, people synthesized their own chemicals to attempt to dye their hair blonde. Most of the time, it didn't work.
