Special mix

[njc]

Hi,

quick question to you all, I want to do my roots today but only have limited stock at home. I use Wella koleston and normally use special mix with my base, I only have colour touch special mix in the shade I need.
Would it be ok on this occasion to mix my permanent base with semi special mix, (it’s only 4cm) and 6%?
Thanks

I probably wouldn’t because they have different pHs and it would offset the lift and deposit of the colour. What is your natural base and what is your target shade?
