Hi--
On a vitiligo forum I go to someone posted that they've finally tracked down the gene for vitiligo and it is the same one for lupus and some other autoimmune conditions. I'll post the article link when I find it again. Anyway, it is thought that vitiligo--loss of pigment, Michael Jackson has it--is triggered in individuals with problems with this gene by some kind of environmental factor. In other words, just because you have the gene mutation, you may never get vitiligo, however, if you have contact with "bad phenols", it can trigger it. Mine hypopigmentation was triggered by a single drop of hair dye. I've lost 50% of my pigment from that one little drop. The vitiligo sites have lists of phenol free hair dyes--henna is safe, as well as drugs and substances that can trigger it. Since it is the same gene as the lupus one, I thought that people here might be interested and maybe, if you want to preserve your pigment, avoid phenol containing hair dyes. I'm doing research to find a good list of those if anyone is interested. Also, this all meshes together with the anti-cytokine research going on for the use of possible interferons and anti-interferons as treatments for various autoimmune diseases. Vitiligo is a symptom of excessive interferon. Anti-interferons cause anti-ds-dna.
