I had a extremely bad allergic reaction to PPD. Therefore,I bought Sanotint hair color, and it was BAD. My scalp was bleeding, itching, red, etc... I've called Vivasan for a refund, and "Bill" from Vivasan was absolutely rude, and refusing to refund my money regardless of my allergic reaction. He said it was my fault not his fault that I have allergic reaction, and he's not accountable for it eventhough Sanotint claimed it doesn't have PPD.
