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 will it take for alopecia areata to fully recover once fuzz has started to grow?

Alopecia areata, once showing new fuzz, usually takes three to six months to return to normal. The appearance of fuzz indicates that the alopecia areata is in the recovery phase. In the early recovery stage, lighter-colored fuzz will grow in the area where hair was lost, and this fuzz will gradually turn into normal hair. During the active phase of alopecia areata, there will be noticeable hair loss, while in the dormant phase, the hair loss will stop. Three to four months after the dormant phase, most patients enter the recovery phase, reaching the stage where this small fuzz appears. Hence, the appearance of such fuzz signifies that the alopecia areata is nearing recovery, and new hair will grow during this phase. There are many causes of alopecia areata; it is important to avoid staying up late regularly.

Do alopecia areata follicles necrotize?

After the appearance of bald patches, they are mostly benign and there won't be any necrosis of the hair follicles. Hair follicle necrosis usually occurs in several situations, such as local trauma or previous folliculitis, and in cases of alopecia areata that have not been treated for a long time, where the cause of the disease has not been corrected, leading to follicle atrophy and eventually necrosis. Once hair follicle necrosis occurs, treatment becomes quite complicated, and some people may never fully recover. Once alopecia areata occurs, it is crucial to seek medical care from reputable medical institutions, undergo proper testing and treatment, avoid spicy and irritating foods, refrain from eating overly flavorful foods, avoid staying up late, and minimize anxiety and stress. Strengthening exercises and enhancing immunity, if consistently maintained, can still lead to recovery.

It can be completely cured eventually, but the treatment period may be lengthy. It's important to enhance your immune system through regular exercise, avoid spicy and irritating foods, and prevent staying up late, anxiety, or stress. A diverse diet rich in vegetables and fruits is recommended, along with appropriate medications, such as Traditional Chinese Medicine or Western medicine.

Will alopecia areata heal itself without treatment?

Most cases of alopecia areata, especially those that have just appeared or in children, generally do not require treatment and can resolve on their own. The prerequisite is to maintain a proper diet and lifestyle habits, eat more vegetables and fruits, ensure children do not become picky eaters or have an unbalanced diet, engage in appropriate exercise, and avoid staying up late. If alopecia areata persists for three months or even longer without signs of self-recovery, it may then be necessary to seek medical intervention using medications or other methods. One should visit the dermatology department of a reputable hospital, where treatment might involve oral medication combined with topical drugs. Other options can include plum blossom needle tapping or local medicinal injections. Employing a variety of treatment methods can often speed up recovery. It is essential to maintain long-term commitment to treatment, typically in courses of three months each, but ultimately, the condition is generally treatable.
