I went to the hairdresser and got my grey hair dyed. I have felt dizzy and confused for the last 2 days since dying my hair. I read that vitamin C can help. I used vitamin C mixed with shampoo on my head and I did notice that the dizziness lessened and some of the dye came out. I have also taken many vitamin C tablets in the last 2 days and am drinking a lot to try and feel better. I am not as dizzy as yesterday, but I am still quite dizzy. What should I do?
