BioKap Nutricolor Delicato RAPID Dark Golden Blond 6.3 Permanent Hair Dye From  £13.49

I’m not sure what the changes are?? But this new version has darkened my hair colour way too dark. I’ve been using the same colour for over 2years and it was a nice golden brown however, exactly the same chosen colours 6.3 is no longer that same colour but a much darker tone and my hair is black / dark brown now ??? I’ve also noticed it used to be 70ml and now it’s 70ml?? Something has changed ?? Very disappointed ☹️
