Which human body part has the fastest-growing cells?
Quick Answer
Hair follicles contain some of the fastest-growing cells in the human body. Scalp hair typically grows about 1 centimetre per month on average.
The Full Story
Hair follicles are among the body structures with very rapid cell division because they continuously produce hair. Scalp hair generally grows around 1 centimetre per month, though the rate varies by person, age, health, and season. Nail cells also grow continuously, but hair follicles are notable for their active growth cycle. This constant renewal is why hair can be cut and still keep growing.
