title: Adolescence
text: Facial hair in males normally appears in a specific order during puberty : The first facial hair to appear tends to grow at the corners of the upper lip , typically between 14 and 17 years of age . It then spreads to form a moustache over the entire upper lip . This is followed by the appearance of hair on the upper part of the cheeks , and the area under the lower lip . The hair eventually spreads to the sides and lower border of the chin , and the rest of the lower face to form a full beard . As with most human biological processes , this specific order may vary among some individuals . Facial hair is often present in late adolescence , around ages 17 and 18 , but may not appear until significantly later . Some men do not develop full facial hair for 10 years after puberty . Facial hair continues to get coarser , darker and thicker for another 2 -- 4 years after puberty .
