You could say I deserve the contact dermatitis that is currently plaguing my scalp. I didn't do the patch test the box insists you take before each application, after all I never had a sensitivity to hair dye before. Well, there is always a first time.
Looks like Henna may be my only option for ridding myself of my much loathed indistinct natural hair colour from now on. Darn.
I guess I learnt something today. RTFM and do as it says. Doh.
