Hair loss on the crown may be alopecia areata, also known as patchy alopecia, an autoimmune disease that causes localized or widespread hair loss. This type of hair loss typically presents as round or oval patches of hairless hair, commonly found on the scalp, but can also occur on other parts of the body. Alopecia areata is characterized by the sudden appearance of round areas of hair loss with well-defined borders, and the surrounding hair may be thinning or turning white.
Alopecia areata can be associated with stress, genetic factors, or immune system abnormalities. Patients with alopecia areata may notice a sudden increase in the area of hair loss, or it may occur after a specific stressful event. Characteristics of alopecia areata also include smooth skin in the affected areas without obvious inflammation or erythema. Alopecia areata is not always patchy; sometimes it can present as diffuse hair loss.
If symptoms continue to spread or are accompanied by significant scalp inflammation, pain, or itching, other possible causes should be considered, such as seborrheic dermatitis, psoriasis, or fungal infections. These conditions may require different treatments, so accurate diagnosis is crucial.
When facing hair loss on the top of the head, it's crucial to pay special attention if the affected area expands rapidly or is accompanied by other symptoms such as pain, itching, or redness.

Individual differences are significant, therefore, a professional doctor's diagnosis and advice are indispensable.
