What Causes Alopecia?
The exact cause of alopecia is unknown, but it is believed to be linked to genetics and environmental factors. It is thought that the body's immune system mistakenly attacks the hair follicles, causing them to shrink and stop producing hair. It is also possible that certain medications, stress, and illness can trigger alopecia.

The most common symptom of alopecia is hair loss, which can be patchy or diffuse. Other symptoms can include itching, burning, redness, and swelling of the scalp.
How Is Alopecia Diagnosed?
Alopecia is usually diagnosed by a physical examination. The doctor may also take a skin biopsy or other tests to rule out other conditions.
How Is Alopecia Treated?
There is no cure for alopecia, but treatments are available to help manage the condition. Treatments may include topical medications, corticosteroids, light therapy, and immunosuppressants. There are also natural remedies that may be beneficial, such as essential oils, nutrition, and stress management.
