What is the average growth rate of human hair per month?

The average growth rate of human hair is approximately 1/2 inch per month. This rate can vary slightly from person to person due to genetics, health, age, and other factors, but 1/2 inch is widely accepted as a general benchmark. Understanding this average is essential for hairstylists, as it helps in planning haircuts, styles, and treatments based on how fast a client's hair is expected to grow. The other rates mentioned, such as 1/4 inch, 1 inch, and 3/4 inch, are not the typical rates of hair growth, making the average of 1/2 inch the most accurate option.
