There are many myths and misconceptions about hair. People often think of hair as simply a cosmetic feature, but hair is actually an important part of the body. Hair has a number of important functions, including protecting the scalp from the sun and wind, regulating body temperature, and providing insulation.
Hair is made up of keratin, a protein that is also found in skin and nails. There are two types of hair: vellus hair and terminal hair. Vellus hair is thin and fine, and it is found mainly on the face and body. Terminal hair is thick and coarse, and it is found mainly on the scalp.
The purpose of hair is to protect the scalp and skin from the sun and wind. The hair on the scalp shields the skin from the sun’s UV radiation, and it also helps to regulate the body’s temperature. The hair on the body helps to insulate the body and keep it warm.
Hair also plays an important role in communication. Human beings use their hair to express emotions and communicate non-verbally. Hair can be used to convey a variety of messages, including dominance, sexuality, and aggression. Hair can also be used to create an impression of personality or character.

Hair is made up of protein called keratin. The hair shaft is made up of three layers: the cuticle, the cortex, and the medulla. The cuticle is the outermost layer and is made up of tightly-packed scales. The cortex is the middle layer and is responsible for the hair’s color and texture. The medulla is the innermost layer and is made up of loosely-packed cells.
Hair growth occurs in cycles. The average person loses 50-100 hairs per day, but new hairs are continually growing to replace them. Hair growth is cyclical, with three phases: anagen, catagen, and telogen.
Anagen is the growth phase, which lasts 2-6 years. Catagen is the transition phase, which lasts 2-3 weeks. Telogen is the resting phase, which lasts 2-4 months. At the end of the telogen phase, the hair falls out and a new hair begins to grow in its place.
