Last time I saw the rheumy, I told him if it was going to fall out anyway, I wanted it to look pretty in the meantime so I dyed it. I swear he wrote "IN DENIAL" in my medical record!
I had heard about the possible connection to triggering lupus initially, but not so much about triggering flares. Hmm. I've been dying for the last couple of years (figured I already had lupus...denial again huh?) and lupus has remained mild. I use the shorter acting versions with natural color. Also I tend to not care what I look like when I don't feel well, thus it's not as frequent as most.
Anyway, grey roots (all in a big clump right in front) are starting to show again, but busy fighting off pleurisy right now, so maybe I'll wait another week!
