Approximately 24 hours ago, I swallowed a bit of hair dye while I was in the shower rinsing it off. I didn t realize it until I started having symptoms similar to the stomach flu, slight fever, diarrhea, stomach ache, and a small head ache. Since it has been about and entire day since it happened, I only have abdominal pain. Do I need to be worried about this? How long until I don t have the hair dye in my system anymore?
