I have finally plucked up the courage to go copper using the loreal magicontrast pure copper and copper red. Has anyone ever used these together? I was thinking to use half and half or would it go too red? I have bought a base 6 to put all over first is this too dark? and should I add a bit of warmth to it? if so what do u suggest? and should I be using a 3% with all these colours as my hair is blonde at the moment. I have also got hair extensions in my hair do you think these would take longer for the colour to take? Thanks in advance xx
