The speed at which your locks grow depends on your genetic make-up and the shape of your follicles.
If you’re of European origin, your hair grows about 1 cm a month — or 0.035 cm a day.
That’s about a sixth of the rate that grass grows during the winter months.

But unlike scalp hair, eyebrows and eyelashes automatically stop growing at 2 cm, fall out and are replaced.
In men, their beards grow at about the same speed as head hair — though for unknown reasons the rate of beard growth speeds up after the age of 40.
