Men’s and women’s hair grows at equal rates on average around half an inch per month. Of course, there are some slight differences from individual to individual, but this isn’t important in determining any greater growth rate in men or women. It is, however, believed that men’s hair grows faster. Usually, men’s hairstyles are considerably shorter than those of women. Differences in length of men and women’s hair are simply cultural, affected by hair care and cutting, not growth rate.
