This is usually from an allergic reation to a chemical. As a hair dresser, I have seen & experienced this many times. Try & use a different type of color, see if it doesnt change. It may also be a sensitivity to heat or chemical also. (Not necesserrily allergy).

Thank you for responding, and thank you to the masters of this site for letting me know you had done so!
I don't seem to be having the RHE too frequently (right now!) I will ask my beautician when I see her next week if she changed chemicals!
