reaction to hair dye

has anyone ever had tiny bumps on their scalp after they dyed their hair? i had some the previous time i dyed my hair. they were a little bit painful when i touched them but most have gone away. should i be worried? how long should i wait to dye again? or should i stop altogether?

Yes, I've had bumps on my scalp after dyeing before.  It was like a rash all over my scalp, and it itched a lot, and hurt if I scratched at it.  At first I thought it was the ammonia in the dye I was using, so I got one with no ammonia, and it still happened :-( .  Because of that, and the fact putting peroxide on wounds has begun to make them worse rather than better, I think I've become allergic to peroxide.  I've been trying to use dyes that have none of either, and it hasn't happened since, but now my choices of dyes are more limited :-( .

I've had bad itchiness and a bit of burning from dying, but only because I dyed my hair straight after shampooing - that was a mistake I'll never make again!!!

You can become allergic to things, even if you've been able to use them with no problems before.  That's why the packages say to always do the allergy test.
