The Lord of the Rings trilogy has some of the most beautiful styles from the movies listed here. Some of them look deceptively simple while being quite intricate in actuality. As with the majority of the movie hairstyles on this site, the original styles all used hairpieces. Most of the styles are easily done on a real head of hair with a little improvisation. The main requirement is long hair; it won't be easy to get the same look with short hair, and some of the styles simply don't work for hair above shoulder length.
