Why Does Blonde Hair Turn Green When Dyed Brown. The only way to fix green hair without cutting it is to cover the green with a warm toned dye. If your hair is medium brown select a medium chestnut color.
Well if she is using box dye this could be her problem if one of the tones is ash. Get orange out of blonde hair. The best thing to do is go to the salon however if that is not possible go to sally s beauty supply and buy your desired level 1 being darkest black do not recommend and 10 being the lightest.
I recently went on holiday and swam in the sea a few times the pool daily and also a river.
I would discourage that. The ash is what gives hair a green tone. Well if she is using box dye this could be her problem if one of the tones is ash. If it does turn green visit the salon.
