Any danger using or touching hair dye often?

Yes, most dyes TOXIC. This is a great question. Few people (including doctors) realize how toxic most hair dyes are. Hair dyes can cause asthma & allergic reactions and are associated with increased risk of certain cancers (like non-hodgkin's lymphoma) & primary biliary cirrhosis, a lethal condition. However, not all dyes are equally toxic- there are safe alternatives like henna. See www.Squidoo.Com/hairdyedangers.
