Hair loss often occurs in old age. The sex hormones in the body change. This also affects the hair on the head. Your hair is getting thinner and falling out more quickly.

The tendency to lose hair is usually congenital, which means you were born with it. This is the most common reason for hair loss. Sometimes certain medications cause hair loss. For example, medications taken for deposits in the blood vessels, or for pain.
