TRIVIAL PURSUITS: How Fast Does Your Hair Grow?

Business closures related to the coronavirus outbreak means some of us may have to forgo getting a haircut for a while.

How fast does your hair grow?

The American Academy of Dermatology says that hair grows about 1/2 inch per month on average.

However, how fast your hair grows will depend on your:

  • Age,
  • Gender,
  • Specific hair type,
  • Overall health, and
  • Other health conditions.

As we grow older, the speed at which our hair grows will slow down to as little as 0.1 inches per month, ScalpMED reports. There is also some proof that men’s hair grows faster than females, although not by much. Studies have found that men’s hair grows about 0.75mm per month faster than women’s hair.

A 2005 study in the journal International Journal of Dermatology also found a difference among races in the rate of hair growth. The average hair growth rate of Asian female participants was nearly 6 inches per year. Comparatively, African female participants’ hair grew 4 inches per year, while Caucasian female participants’ hair grew a little more than 5 inches per year. The hair growth rate of the male participants didn’t significantly differ from that found for women.

Research has also suggested that hair grows more quickly during the summer.
