Hi everyone I just had a quick question. I used Natural Instincts hair coloring kit a couple days ago to darken my hair. (my hair is naturally medium to dark brown but I had some light brown almost blond highlights I wanted to get rid of) I like my hair dark dark brown almost black during the winter and I didn't leave the dye on long enough so the blondish pieces are still not as dark as I would like them to be. (My hair doesn't look all weird or anything, just not as dark as I wanted). Thus my question is, can I dye it again (I would probably do it in about two weeks) or should I wait the 4-6 weeks that the box says? Thanks!
