What Is Alopecia?
Alopecia is the medical term for hair loss. It can affect the scalp, face, or other areas of the body and may develop gradually or suddenly. Hair loss can result from genetics, autoimmune diseases, hormonal changes, medications, nutritional deficiencies, stress, or certain medical conditions.
The severity of alopecia varies from small patches of hair loss to complete loss of scalp or body hair.

Treatment depends on the type and cause of hair loss. Options may include medications, corticosteroid injections for certain autoimmune conditions, nutritional support, changes in hair care practices, treatment of underlying medical conditions, or other therapies recommended by a healthcare provider.
