Human hair growth
The three stages of hair growth are the anagen, catagen, and telogen phases. Each strand of hair on the human body is at its own stage of development. Once the cycle is complete, it restarts and a new strand of hair begins to form. The rate or speed of hair growth is about 1.25 centimetres or 0.5 inches per month, or about 15 centimetres or 6 inches per year.
Hair fetishism
Hair is one of the defining characteristics of mammals. In humans, hair can be scalp hair, facial hair, chest hair, pubic hair, axillary hair, besides other places. Men tend to have hair in more places than women. Hair does not in itself have any intrinsic sexual value other than the attributes given to it by individuals in a cultural context. Some cultures are ambivalent in relation to body hair, with some being regarded as attractive while others being regarded as unaesthetic. Many cultures regard a woman's hair to be erotic. For example, many Islamic women cover their hair in public, and display it only to their family and close friends. Similarly, many Jewish women cover their hair after marriage. During the Middle Ages, European women were expected to cover their hair after they married, and according to the New Testament, a christian woman should cover her head while in a church or in prayer.
