The factors contributing to alopecia areata are complex, such as frequently eating spicy and irritating foods, or food with strong flavors, consistent late nights, anxiety, stress, and poor mood, which can all lead to the condition. Additionally, some people often experience folliculitis, abscesses, or cysts on the scalp, damaging the hair follicles and leading to alopecia areata. Only a minority of cases are somewhat related to genetic heredity. Therefore, the treatment of this disease is comprehensive, involving not only oral and topical medications but also a variety of other approaches. With long-term persistent treatment, it is possible to completely cure the condition. Developing good dietary and lifestyle habits also aids in treatment.

Can alopecia areata dye hair?

There are many causes for alopecia areata, most of which are related to diet and lifestyle habits. For example, frequently being picky about food, having an unbalanced diet, or consuming spicy and heavily flavored foods can trigger it. Long-term staying up late, anxiety, stress, and being in a bad mood can also cause it. Once alopecia areata occurs, try to avoid dyeing or perming your hair, as these chemical materials can potentially irritate the scalp and exacerbate the condition. It is recommended to seek proper treatment immediately after discovery, otherwise the condition might worsen, leading to complete hair loss or loss of eyebrows. Regular consumption of beans and maintaining a healthy diet and sleep schedule are also advised.

How long does the hair loss phase of alopecia areata usually last?

The shedding phase of alopecia areata generally lasts about three months. Alopecia areata refers to the sudden occurrence of patchy hair loss on the top of the head, usually caused by excessive mental stress, fatigue, and disorders of the immune system. Alopecia areata typically arises when various factors cause the hair follicles on the scalp to shift from the growth phase to the resting phase, resulting in the hair no longer growing and subsequently falling out extensively. The occurrence of alopecia areata is also somewhat related to genetics. If dieting leads to malnutrition, alopecia areata may also occur. The clinical manifestation of alopecia areata is the appearance of round or oval patches of hair loss on the top of the head. Some occur individually, while others may appear in multiples, varying in size and without any subjective symptoms. If alopecia areata occurs, it is advisable to seek diagnosis and treatment in the dermatology department of a standard hospital.
