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.
This part is called the hair shaft and it's the part of your hair that can get long. Most kids' hair grows about 1 centimeter a month. About 85 out of 100 hairs on your head are growing (the anagen phase) at any time. When a hair is done growing it goes into its resting (telogen) phase and eventually falls out. Usually, 15 out of 100 hairs on your head are in the resting phase.
