Introduction
A sudden small patch of hair loss at the back of the head may indicate alopecia areata. Most patients with mild alopecia areata can either recover spontaneously or achieve full recovery after proper treatment. In daily life, maintain good living habits, keep a regular schedule, and avoid staying up late. Eat a light diet low in oil, salt, and fat, and avoid spicy or irritating foods. Keep the scalp clean by washing hair regularly, and avoid scratching with fingers.

Alopecia areata is a hair loss condition associated with psychological factors, autoimmune responses, and allergies. Its typical symptoms include the sudden appearance of round or oval bald patches with clear boundaries, varying in number. Therefore, a sudden bald spot on the back of the head could be a sign of alopecia areata. Most individuals with mild forms of this condition can recover on their own or with standardized treatment.
For patients with a single lesion, few bald patches, and limited affected areas, observation during follow-up visits may be sufficient, or topical medications may be used. Commonly prescribed topical treatments include halometasone and clobetasol propionate. Intralesional corticosteroid injections—such as compound betamethasone injection or triamcinolone acetonide injection—are also effective options. Minoxidil can also effectively treat patients in the stable phase or those with smaller areas of hair loss.
In daily life, maintain healthy habits, keep a regular sleep schedule, and avoid staying up late. Eat a light diet low in oil, salt, and fat, and avoid spicy or irritating foods. Keep the scalp clean by shampooing regularly and avoid scratching with fingernails. If severe alopecia areata develops, seek medical attention promptly and follow professional medical guidance for treatment.
