Hi, I have been doing really well with my HA for the last month, but this morning I finally gave in and dyed my hair, it is not a permanent one and I did the 48 hr patch and had no reaction. I did it about 9.30 am (over 8 hrs ago) and as soon as I did it I had a full on panic attack and am convinced I am going to have a serious reaction as I have read about a few lately! I am convinced my scalp is hurting and I have a headache and am in a real panic.... am worried my face is going to swell up and I am going to die...... I know its sounds really silly..... would I have had a severe reaction by now if it was going to happen??? Please can anyone reassure me as I am SO scared..... :(
