Hair

"I know what you are going to say. I changed my hair." "It's nice that way."

- Leia Organa and Luke Skywalker

Hair was a collection of pigmented thread-like strands growing from the skin of certain species, including humans and Weequays. The thick coat of hair of certain life-forms was also referred to as fur. Such species included the Wookiees of Kashyyyk and the Talz of Orto Plutonia. Hair came in a great variety of colors, lengths and thicknesses. As exemplified by the case of Obi-Wan Kenobi, hair lost its hue with old age. Hair could be styled in a vast number of ways for practical or aesthetic reasons. The human weapon experts Sabine Wren used to keep her hair short because it would often get sweaty under her Mandalorian helmet. Nonetheless, she also did dye jobs to add rainbow streaks in her hair. Besides conventional dyes, there existed a Mon Cal microplankton that would bond with each strand of hair, giving it a bioluminescent glow. The queens of Naboo often sported very intricate hairstyles. A product known as hair gel could be applied to tame any unruly hairs one may have.

The Nightsisters of Dathomir could inflict a curse on a given individual by creating a waxen effigy of that person. The creation of the effigy required a lock of the intended victim's hair.

Militaries typically had requirements regarding the hair style of their officers. For example, close-cropped hair was a requirement in the Galactic Republic's military. In the Galactic Empire, officers often cut their hair short for optimal efficiency, but were allowed to keep it long on the condition that they wore it pinned back in tight braids.

Female porgs crafted nests by using hair, fiber or grass.

Appearances
Hair appears in almost every Star Wars work. Hair is also referred to in virtually every Star Wars novel and many short stories, since describing someone's hair is often used to describe a character physically to the reader.
