Is there anyway I can darken my hair? I used henna and I had blonde highlights from 3 months ago (my hair is naturally medium brown) and my hair has gone auburn with fire red highlights and I really want to darken it!! Any sugestions? Would using the henna mixed with coffee again darken it? I dyes it a day ago.

"Henna" is a curse word to hairstylists. It is difficult to deal with, and rarely does well with other types of hair color. It's worst trait is that it is a "natural" way to color hair. See a professional hairstylist that works with an organic color system if you are looking for a more natural way to color your hair. Www.organiccolorsystems.com may be able to help you find a stylist in your area that uses organic hair color. Henna will give you more headaches than happiness in the long run.
