The most common diagnostic methods for vitiligo currently are the Wood's lamp and a dermatoscope. If white patches appear on the face, it is best to visit the dermatology department of a formal hospital for an examination with a dermatoscope and Wood's lamp, which can essentially determine whether it is vitiligo. If the white patches appear around the mouth, beside the nose, or near the eyes, there is a higher probability that these are vitiligo. If the white patches develop on the eyebrows or where there is hair, and if the hair also starts turning white, it can generally be confirmed as vitiligo. If diagnosed with vitiligo, it is necessary to seek treatment promptly. Generally, a combination of oral and topical medications along with 308 laser treatment can be quite effective. Additionally, some facial white patches may simply be pityriasis versicolor, which is somewhat related to fungal infections.

Does vitiligo spread through close contact?

Vitiligo is a type of autoimmune systemic disease. The most common causes of the disease are decreased immunity, genetic heredity, copper deficiency in the body, or local injuries. This disease is not contagious, which means that contact or living together will not transmit it to each other, and this can be reassured. However, treating this disease can be quite troublesome, time-consuming, and slow in showing results. Once diagnosed, it is essential to seek treatment in the dermatology department of a reputable hospital. Treatment options can include oral medication combined with topical drugs and 308 laser treatment, which tends to have quicker effects. During and after the treatment, it is necessary to continue using medication to consolidate the effects, enhance physical exercise, boost immunity, and consume more black-colored foods. Foods rich in vitamin C should not be consumed in excess.

What are the characteristics of the stable period of vitiligo?

The stable phase of vitiligo is defined as a period of at least six months, or even more than a year, during which there are no changes in the localized white patches on the body, regardless of whether treatment is administered or not. During this phase, the white patches neither progress nor recover. Treatments during the stable phase are generally not very effective; oral medications, topical applications, and even treatment with a 308 laser typically show little change. The most common treatment plan during the stable phase still involves melanocyte transplantation. Patients should visit a dermatology department at a certified hospital to get a proper diagnosis and specific treatment. During the treatment period, it is important to enhance physical exercise to boost immunity, consume foods rich in black pigments, and limit intake of foods high in Vitamin C. After recovery, measures should be taken to prevent relapse and consolidate the treatment results.

Will vitiligo recur after skin grafting?

Vitiligo generally enters a stable phase after which skin grafting is quite effective. The stable phase is typically reached when, after about a year of treatment, there are basically no changes, no worsening or improvement in the condition, which is referred to as the stable phase. Using the method of skin grafting to directly implant melanocytes into the depigmented regions tends to be effective. Generally, after skin grafting, melanin quickly proliferates and extensively covers the depigmented areas. However, the factors causing this disease are quite complex. Some individuals, especially those with lower immunity, might experience recurrence even after a successful graft. Therefore, personal health status and clinical evidence should be considered individually.

What is generalized vitiligo?

Generalized vitiligo, as opposed to localized vitiligo, generally covers larger areas and can appear on various parts of the body, while localized vitiligo typically occurs in only one area, such as the palms or around the mouth. Once this disease is discovered, especially generalized vitiligo, it must be treated properly; otherwise, the affected area can increase, making treatment more difficult later on. Treatment should be sought at a reputable hospital's dermatology department, where a combination of oral medication, topical medication, and 308 laser therapy can be effective. During treatment, it's important to exercise to strengthen the immune system, avoid foods rich in vitamin C, and consume more dark-colored foods, which can help in the production of melanin.

What are the symptoms of vitiligo on the head?

Vitiligo has numerous causative factors, including diminished immune function, genetic predisposition, copper deficiency in the body, or localized trauma. Vitiligo commonly manifests on the scalp as white, patchy areas of skin, and the hair attached to these patches may also turn white. In some cases, the affected area may gradually expand, spreading to the face or the trunk of the body. Once white patches are observed on the scalp, and the hair in these patches turns white, it is strongly suspected to be vitiligo and should be medically treated at a dermatology department in a reputable hospital. If the affected area is small, complete recovery is possible with proper treatment. During treatment, it is important to exercise regularly and boost the immune system.
