With the arrival of spring, factors that trigger vitiligo are increasing, raising the likelihood of recurrence and spread of white patches. The following five symptoms often indicate that vitiligo may be spreading, warranting heightened vigilance and timely intervention.

With the arrival of spring, factors that trigger vitiligo are increasing, raising the likelihood of recurrence and spread of white patches. The following five symptoms often indicate that vitiligo may be spreading, warranting heightened vigilance and timely intervention.

1. Expansion of Existing White Patches

After vitiligo recurs in spring, the healing and recovery speed of previously treated patches may slow down. The affected areas may gradually extend into normal skin, and the edges of the patches might become less defined. Pigment islands that had started to reappear may fade, restoring the patches to their original depigmented state. During this phase, close monitoring of changes in the patches is essential. If signs of spreading are observed, it indicates a recurrence, and anti-relapse treatment should be initiated promptly.

2. Fusion of Adjacent White Patches

Adjacent white patches may merge, forming larger depigmented areas. In severe cases, the condition may spread to multiple other areas, potentially developing into generalized vitiligo. For managing progressive vitiligo, the priority is to stabilize the condition and prevent it from worsening. Active cooperation with treatment is crucial when the patches are expanding.

3. Reappearance of Previously Healed Patches

After systematic treatment, some individuals may have seen their white patches return to normal skin tone. However, spring often brings a risk of recurrence, which may be linked to inadequate anti-relapse therapy or lack of consolidation treatment during the earlier stages. During this period, in addition to undergoing anti-relapse treatment, it is important to minimize exposure to triggering factors such as sun exposure, skin injuries, and allergies.

4. Whitening of Hair in Affected Areas

When vitiligo recurs, it may affect the hair in the depigmented areas, causing it to turn white. This can include hair on the scalp, eyebrows, or eyelashes. Whitening of hair signifies more severe loss of melanocytes in the affected areas and requires immediate attention.

5. Presence of Hidden or Incipient White Patches

In some cases, the originally affected areas may appear normal to the naked eye, but hidden or newly emerging patches may be detectable under specialized instruments. To check for such hidden patches, it is advisable to undergo a systematic examination at a hospital, such as a full-body Wood’s lamp or skin CT scan. This helps identify any invisible depigmented areas and supports effective anti-relapse treatment during spring.
