What are the early symptoms of vitiligo?

The initial manifestations of vitiligo mainly include: 1. Skin color changes: Irregular white patches appear on the skin. These patches usually have clear boundaries and irregular shapes. They can occur on multiple areas such as the face, neck, chest, back, arms, and legs. In the early stage, the patches may be small, but they may gradually enlarge as the condition progresses. 2. Abnormal skin sensations: Some patients may experience localized skin sensitivity or pain, especially when the patches are exposed to sunlight. In addition, a few patients may experience mild itching. 3. Hair changes: Vitiligo may cause the hair in the affected areas to turn white or fade. This is due to damage to the pigment cells, which affects pigment production in the hair follicles. 4. Other symptoms: Some patients may also experience symptoms such as erythema and edema during the early stage of vitiligo. This may be due to vascular dilation and inflammatory responses caused by immune reactions.
