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 removal
Hair typically grows all over the human body. Hair can become more visible during and after puberty and men tend to have thicker, more visible body hair than women.
Both men and women have visible hair on the head, eyebrows, eyelashes, armpits, pubic region, arms, and legs; men and some women also have thicker hair on their face, abdomen, back and chest. Hair does not generally grow on the lips, the underside of the hands or feet or on certain areas of the genitalia.
