Normally, the color of hair, skin and eyes is determined by melanin. Vitiligo occurs when the cells that produce melanin die or stop functioning.
Vitiligo signs include:
- Skin discoloration
- Premature whitening of the hair, eyelashes, eyebrows or beard (usually before age 35)
- Loss of color in the tissues that line the inside of your mouth and nose (mucous membranes)
- Loss of or change in color of the inner layer of the eyeball (retina)
- Discolored patches around the armpits, navel, genitals and rectum
