Hair loss disorders refer to conditions that lead to the thinning or complete loss of hair on the scalp or other areas of the body. Common types include androgenetic alopecia, often known as male or female pattern baldness, and alopecia areata, an autoimmune disorder that causes patchy hair loss. These disorders can affect individuals of all ages and genders. Various factors contribute to hair loss, including genetics, hormonal changes, medical conditions, and stress. Treatments may involve medications like minoxidil or finasteride, lifestyle changes, or hair restoration procedures. Understanding the underlying cause is essential for effective management.
