Does African American Hair Grow?

Of course black hair grows.  Hair, regardless of race, grows about 1/4" to 1/2" per month.  Black people tend to have shorter hair because it can be hard to RETAIN this growth.  If hair did not grow, there would be no need to retouch a perm or hair coloring.  By the way, hair grows from the roots. 

 Some may wonder why black hair doesn't seem to grow long.

African American hair can be dry and if it breaks at the same rate that it grows, the growth will not be evident. The hair must be taken care of very carefully to maintain its health and black people, in general, are just figuring out what's necessary.

Also, 6 inches of natural kinky curly African American hair will look much shorter than 6 inches of straight hair.
