What is normal hair loss in old age referred to?

Normal hair loss associated with aging is referred to as alopecia senilis. This term specifically describes the gradual thinning or loss of hair that commonly occurs as people age. It is a natural part of the aging process and can affect both men and women. Understanding this concept is important in the field of barbering, as acknowledging the norms of hair loss allows barbers to provide appropriate services and advice to clients who may be experiencing these changes.

The other terms listed refer to different types of hair loss: alopecia areata is an autoimmune condition that causes sudden hair loss in patches; alopecia totalis results in total loss of hair on the scalp; and alopecia universalis is the complete loss of hair on the entire body. Knowing these distinctions is crucial for barbers to understand the various conditions affecting hair and how to address them with clients.
