How Fast Does Your Hair Grow?
For men who are becoming a little bald, hair doesn't grow fast enough! But in the case of a young boy, the hair seems to grow too fast! The rate at which hair grows has actually been measured and found to be about 1.5 cm (half an inch) a month.
The hair doesn't grow at the same rate throughout the day but seems to follow a kind of rhythm.
At night, the hair grows slowly but as day begins, this is speeded up. Between 10am and 11 am the speed of growth is at its greatest. Then the hair grows slowly again. It picks up speed between 4pm and 6pm and then the growing slows down again.
Of course, these variations in the speed of growth are so tiny that you cannot possibly notice them. So don't expect to stand in front of the mirror at 10 am and be able to watch your hair sprouting up! Not all people have the same amount of hair! Blond people tend to have finer hair but more profuse than dark people. Red-haired people have the coarsest hair and fewest hairs.
