Alopecia is a medical condition that causes hair loss, which can occur on the scalp or other parts of the body. It can affect people of all ages and genders, and the severity of hair loss can vary widely. The most common type is Alopecia Areata, an autoimmune disorder where the immune system mistakenly attacks hair follicles, leading to patchy hair loss. There are other forms of alopecia, such as Androgenetic Alopecia, often referred to as male or female pattern baldness, which is linked to genetics and hormonal changes. Treatment options include medications, topical solutions, and in some cases, hair transplant surgery, but results can differ from person to person.
