Thanks all...I feel much better and I'm glad it's not just me.
In a related incident, the hairdresser (a friend) is here to do my highlights and about 5 minutes after the middle sections of foil were put in my head was on fire...I actually cried from pain. We had to wash off ultra-quick and the colour had weirdly taken already. Apparently * week (is that the norm reference?!) can do that to people...weird!
