Overview
Alopecia is a medical condition characterized by hair loss from the scalp or other parts of the body. It can be caused by a variety of factors, including genetics, hormonal imbalances, autoimmune disorders, certain medications, and physical or emotional stress. Alopecia can take many forms, including androgenetic alopecia (male or female pattern baldness), alopecia areata (an autoimmune disorder), telogen effluvium (a disruption to the normal hair growth cycle), and others. There is no one-size-fits-all definition of alopecia as it can manifest in different ways and the causes can vary.
