Hair slows down or speeds up growth depending on various factors, and differs from person to person in any case; so any estimates cannot be used as a prediction for personal growth rates. One oft-cited figure is 0.44mm a day; another is half an inch per month. Clarence R. Robbins in Chemical and Physical Behavior of Human Hair (Springer, 2002) p. 9, states confidently: “Hair grows at about 16cm/year (~6.2 inches/year) on the vertex or the crown area of the scalp. It grows at a slightly slower rate (~14cm/year) in the temporal area and generally at even slower rates on other body regions (e.g. ~10cm/year) in the beard area”. Robbins also states that hair growth may slow down gradually due to ageing.
