Before you read: I am not a professional, and have not been trained in dyeing at ALL. I just have common sense, I know how to research, I’ve self-taught myself many things, and I have self-dyed my hair many, many times before so I have a general idea of how to dye my OWN hair. If you have issues with your hair dye, I cannot help you other than to Google the problem. Please go to a PROFESSIONAL for help. I read up on this particular brand of dye and how well it worked quite a bit before going ahead with it, so while I’m confident in what it can do based on many online reviews and my own experience, I have to emphasize: I cannot guarantee it will work the same way for you! Do some research of your own, evaluate your own hair, and proceed with much caution.
Also, while I did not have to pre-bleach my hair, as in, I didn’t have to lighten it and THEN apply color, this dye DOES have bleach in it. So if your hair is sensitive to bleach or particularly fragile, you might want to reconsider.
