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.
It may grow faster or slower depending on your age, your genetics and your hormonal state (pregnancy seems to have an affect on hair), but half a millimeter per day is a good average. What this means is that the maximum growth rate for hair is about 6 inches (15 cm) per year.If you have short hair and are thinking, It sure would be nice if I had hair down to my waist, then you are going to have about a four-year wait!
