How do you prevent vitiligo?

As there are no exact causes for vitiligo, there are no specific ways to prevent the condition, as stated by WebMD. The destruction of pigment cells can only be treated, not avoided.

Vitiligo can be a hereditary disorder or brought on by stress, sunburn or due to an autoimmune illness that causes the body to attack the melanocytes, the cells that produce melanin. Worsening of the disorder can be prevented through the use of certain medications, light and laser therapies, and various surgeries for more extreme cases, according to Mayo Clinic. Some alternative therapies, such as taking Ginkgo biloba, may help to restore skin color in some individuals.
