Hair is a thick, fibrous protein filament that grows from follicles in the dermis of the skin. It is one of the most recognizable features of mammals, distinguishing them from other organisms, and serves several important functions in humans including protection, thermal insulation, sensory input, and communication. Hair is present in many mammals and other animals, although it is sparse on some, such as elephants and rhinoceroses.
Most of the human body is covered in hair. The exceptions are the palms of the hands and soles of the feet, and a small area around the eyes called the eyebrows. The primary function of hair is to protect the skin and to act as a thermoregulator, trapping a layer of air to add insulation. Hair also acts as a sensory input by sensing motion and touch, and is able to detect light pressure.
The color and style of a person’s hair can give insight into their character. For example, blondes are sometimes stereotyped as dumb or gullible, while redheads are often considered to be sexy or sassy. The texture of a person’s hair can also tell us a lot, whether it is coarse and rough or fine and smooth. People with very long hair might choose to keep it loose and flowing, while others may choose to tightly braid or bind their locks.
It is not uncommon for hair to be damaged by chemical treatments, heat styling tools, and harsh shampoos. This damage can leave the hair brittle or fragile, and can even result in permanent loss of the hair. Using the right hair products and knowing how to care for the hair can help prevent this type of damage.
There are a variety of styles for hair, from a casual ponytail to a formal upsweep. Many people also use accessories such as hair clips, barrettes, headbands, and hair extensions. It is helpful to have an understanding of the anatomy of hair, including its thickness and growth rate. It is also useful to know the difference between short and medium hair, which is usually defined as above shoulder length.
Adding details about the movement of a character’s hair can be an effective way to bring them to life. For example, a person might scratch their scalp or twist their hair as a sign of nervousness. Similarly, a person might brush their hair compulsively or comb it as a way to relieve stress or anxiety.
It can be easy to forget about body hair when describing a character. However, if used well, body hair can provide an excellent sense of a person’s personality and their worldview. Including details about the way a person moves their hair can also inform the reader a lot about who they are, and can be a powerful tool when bringing them to life in a story.
