The chemical is known as PPD, it is commonly found in a lot of hair dyes. I am acutely allergic to it. Take a look at http://www.hennapage.com/henna/ppd/
When I had my bad reaction in 2000, I found that Aloe Vera Gel was soothing.
And when people say to test it 24hrs beforehand they are wrong as the reaction can take up to 10 days to appear.
