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.

What should be paid attention to in daily life for alopecia areata?

Alopecia areata has many causes and complex contributing factors, and each person's triggering elements differ. Besides seeking treatment from qualified medical institutions, it is crucial to avoid spicy and stimulating foods, overly salty or strongly flavored foods, as well as to refrain from staying up late, feeling anxious, stressed, or upset. It is essential to enhance physical exercise to boost immunity and to avoid using irritating hair products such as gels or conditioners, or frequently perming or dyeing the hair, as these do not aid in treatment. Another important aspect is the need for long-term and persistent treatment because the effects of treatment for this condition are very slow to manifest. A single treatment cycle requires at least three months, but with long-term commitment, it is entirely possible to achieve a complete cure.

What should I do if alopecia areata has expanded?

When there is an expansion of alopecia areata, local injections of corticosteroids can be used. The treatment with corticosteroids is a kind of occlusive therapy, primarily involving injecting corticosteroids into the area of hair loss. This can suppress inflammation and immune responses around the hair follicles, enabling hair growth and potentially preventing the expansion of alopecia areata. However, some individuals may experience localized skin atrophy after corticosteroid injections, and some may experience depigmentation. Therefore, when alopecia areata is expanding, it is advisable to seek timely treatment at a dermatology department in a reputable hospital. Under the guidance of a doctor, treatment can include topical application of minoxidil solution, or the use of compound preparations like compound styradan tonic for hair growth, as well as oral medications such as cysteine tablets, compound glycyrrhizin capsules, and treatment based on Traditional Chinese Medicine diagnosis and differentiation.

How long does it generally take for a small patch of alopecia areata to recover?

Alopecia areata, commonly known as "ghost shearing", is often related to immune factors in its causes and mechanism of onset. It is important to rest and provide symptomatic treatment with immune modulation. Generally, recovery can be expected within about a month. Oral medications such as cysteine tablets, folic acid tablets, vitamin B6 tablets, and pimecrolimus granules can be taken. In the area affected by alopecia areata, topical application of dermatan sulfate polysaccharide cream, tacrolimus ointment, combined with the use of minoxidil solution is recommended to promote local circulation and thereby facilitate hair regrowth. Additionally, other physical therapy measures can be supportive, including traditional Chinese medicine treatments such as plum-blossom needle tapping and local intense pulsed light therapy. (Medication should be used under the guidance of a doctor.)

What causes alopecia areata?

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.

Which vitamins should be supplemented for alopecia areata?

Alopecia areata is a type of sudden, localized, patchy hair loss, the cause of which is not entirely clear and is not simply related to vitamin deficiency. It is currently believed to be related to genetics, emotional stress, over-tension, extreme joy or sorrow, as well as endocrine disorders, autoimmunity, and may fall within the category of polygenic diseases. In treatment, it is generally important to eliminate possible triggering factors, ensure a balance between work and rest, and avoid staying up late, with a recommended bedtime at 11 o'clock. Topical treatments can include the use of minoxidil, or a local injection of steroids, while systemic treatments can be supported by taking cysteine, calcium pantothenate, vitamin B, etc., which aid in hair growth. For rapid and widespread hair loss, including total baldness and universal baldness, oral steroid therapy can be used, but it is important to be aware of the potential systemic side effects associated with long-term use of steroids. Traditional Chinese medicine treatments such as nourishing blood and hair growth capsules, Qi Bao Mei Ran Dan, and Biotin Peptide Tablets may also be tried for alopecia areata.
