Additional info, added Monday August 25 2008, 8:43 pm: also what does ammonia mean? is it bad?. Want to answer more questions in the Miscellaneous category? Maybe give some free advice about: Fashion and Styles? LM answered Tuesday August 26 2008, 8:21 am: It means that if your hair is greying [like when people age, their hair loses its color] you shouldn't use certain colors because it'll look unnatural. Lots of colors labeled 100% grey coverage will work on hair that isn't grey too.
Ammonia is a common ingredient in hairdye. It can be drying, but ammonia-free products might not last as long. [ LM's advice column | Ask LM A Question ]
