I have been using this product in the shade 'Darkest brown' for about 5 months now. The last time I dyed my hair with it was around 10th June so I have the usual root show (even though it's semi permenant). I saw an advert for a new shade in this range called 'Black cherry' and fell in love with it. If I dye my hair with the new shade, over the old shade, will it be an even colour?
My friend said i'd risk having a massive pink line where my strawberry blonde roots are at the moment..and i'm not sure if it's just a joke.
Anyone had any experience of this?
Thank you
