I have just tried to dye the wife’s hair with your age defy number 6 light brown dye and your product has made no difference to the amount of grey still showing. I followed the instructions carefully as we have not used this product before and when mixing the two bottles together I noticed that the fluid that I was applying to the hair was white with no hint of any colour at all. My wife as I am are very disappointed with the results. Please find two photos before and after attached .
