What is the average growth rate of human hair?

The average growth rate of human hair is approximately half an inch per month. This rate can vary slightly among individuals due to a range of factors including genetics, health, and age. Understanding this growth rate is essential for cosmetologists as it affects how frequently clients may need haircuts or color touch-ups, and it helps in planning hair treatments and styling techniques. The half inch per month figure allows professionals to set realistic expectations for clients regarding hair growth and styling routines.
