The average human head has more than 100,000 healthy hairs, and many people have well over 150,000. Typically, you may lose around 50-100 of these hairs every day, which isn’t noticeable. However, once you start to lose well over 100 individual hairs daily, your hair loss starts to affect your appearance. Both men and women are affected by hair loss, but in different ways. For example, while it’s common for men to have a noticeable loss on their hairline or crown, women tend to experience thinning hair in a more random, widespread pattern. Women also usually have localized loss because of repeated hair trauma, such as from hair being pulled tightly back in a ponytail or bun.
