I dyed my hair today, same colour and make as I always use so didn't bother with a test as have been using it for an age. After it had been on about 10 minutes the top of my head started to sting something rotten, it didn't get any worse but was certainly sore and bothersome.
Obviously I went into the shower and rinsed it out straight away, but it didn't really stop stinging until I shampooed my hair. Would I suddenly be having a reaction to it after such a long time? Please tell me I can still dye my hair? I am SO grey and have to colour it!
