What type of hair loss is typically irreversible and occurs during the aging process?

Androgenetic alopecia is characterized as a type of hair loss that is typically irreversible and commonly associated with the aging process. It is also known as male or female pattern baldness, depending on the gender of the individual. This condition is influenced by genetic predisposition and hormones, particularly androgens, which can lead to a gradual thinning of hair and eventual loss. It usually follows a predictable pattern: in men, it often starts at the temples and crown, while in women, it tends to distribute more evenly across the scalp.

The nature of androgenetic alopecia involves permanent changes to hair follicles, resulting in miniaturization of the hair and overall hair thinning. This means once the hair is lost due to this condition, it does not spontaneously regrow, reinforcing its classification as an irreversible type of hair loss that can become more pronounced with age.

In contrast, other types of hair loss, such as telogen effluvium, involve temporary shedding and can be reversible once the underlying cause is addressed. Alopecia senilis, while sometimes referenced, is a less commonly used term and is not as widely recognized in the literature as androgenetic alopecia. Traction alopecia occurs due to prolonged tension on the hair and can be reversible if the
