How many hair follicles does an average adult have?

An average adult has about 100,000 to 150,000 hair follicles on their scalp. Throughout the entire body, including areas like the arms, legs, and face, the total number of hair follicles can be in the millions. The exact number can vary based on factors such as genetics and ethnicity. Each follicle typically produces one hair strand, although some can produce multiple strands.
