Any danger of cancer from neutrogena coal tar shampoo to use daily for 2 wks 4 hair loss from seborheic dermatitis ? thought i read it was questnable?

2 weeks is fine: Here in California, the law requires Cancer Warning signs everywhere, because everything we eat, touch, breathe can cause cancer. That's the nature of life, everything on Earth can cause cancer... but the true question is, how likely? So, 2 weeks of any shampoo sold in America should be fine. No worries. Breathing the engine exhaust on the way to the store and back is likely to be more dangerous.
