Hair work, or jewelry made of human hair, was in fashion during most of the 19th century and a few decades into the 20th. It disappeared when short skirts and the bob became stylish around 1925.

There are several reasons why hair work was unbelievably popular for over a century. Human hair does not decay with the passing of time as most other materials. It has chemical qualities that cause it to last for hundreds, yes, thousands, of years.
