What is average hair length by country?

As an AI language model, I do not have access to current data about average hair length by country. However, according to a survey conducted by the market research company OnePoll in 2020, the average hair length for women in the United States is about 15 inches, while the average hair length for men in the United States is about 6 inches. These figures may vary significantly depending on individual factors such as age, ethnicity, and cultural preferences. It is also worth noting that hair length can change over time depending on factors such as diet, stress, and medical conditions.
