In Progress

Vitiligo constitutes one of the most frequent pigment disorders, affecting about 1% of the world's population, with no preference of race, age, gender or country. It commonly starts to manifest around the second decade of life, with a gradual progress of depigmentation, mostly due to loss of melanocytes.

Symptoms

Half of people with vitiligo develop patches of de-pigmented skin appearing on extremities before their 20s. The patches may grow, shrink, or remain constant in size. Patches often occur symmetrically across both sides on the body. Occasionally small areas may repigment as they are recolonised by melanocytes. The location of vitiligo affected skin changes over time, with some patches re-pigmenting and others becoming affected.

In some cases, mild trauma to an area of skin seems to cause new patches - for example around the ankles (caused by friction with shoes or sneakers). Vitiligo may also be caused by stress that affects the immune system, leading the body to react and start eliminating skin pigment.

Vitiligo on the scalp may affect the color of the hair (though not always), leaving white patches or streaks. It will similarly affect facial and body hair.
