How long does it take for hair to grow????
Lanugo, the fine hair that covers nearly the entire body of embryos
Vellus hair, the short, fine, "peach fuzz" body hair that grows in most places on the human body in both sexes
Terminal hair, the fully developed hair, which is generally longer, coarser, thicker, and darker than vellus hair
Depends on where on the body the hair is, and whether u are male or female.Growth cycles tend to be longer for women before the hair falls out by it self.
For example scalp and facial hair grows about 1/10 of an inch perday average, so just fo the math. 10 days = 1 inch. 365/10 = 36.5 inches. so a hair can grow just over 3 ft in one year.
So figure in one month, about 3 inches.
