How many hairs are on the human head?

Estimates put the typical scalp at around 100,000 hair follicles. Natural hair colour makes a noticeable difference: blondes tend to have the most, often around 140,000 to 150,000, while redheads average closer to 90,000 but with thicker individual strands. People with brown or black hair generally fall around 100,000 to 110,000. It is normal to shed about 50 to 100 hairs a day, since each follicle goes through cycles of growth, rest and shedding. The growth phase can last from two to seven years, which limits how long a person’s hair can grow.
