Hey sleeps I dyed my hair red a few weeks ago and of course I didn't do a test patch either. When it first went on it was purple and I began to freak out, afterwards it was bright red, but now it's calmed down and looks nice! I did feel some slight itching for the first day. I hope you are happy with your new hair color. I'd take some benadryl or something and maybe washing your hair a few times in a row might help get some of the dye out *hugs*
