L'Oréal Diactivateur-can you mix volumes?

[Faithoj]

Hi
I have Diactivateur 6 vol but the colour didn't take well on greys. Thinking about trying 9 (and possibly 15 if that doesn't work) but was wondering if I buy 15 can I mix this with 6 to come up to about a 9 vol?
Thx

Yes, just don't dilute it with water.
Do you mean 6 vol or 6%?
Usually, you use 6% (20 vol) to cover grey.

6vol won't cover Grey hair! 15 all the way ,

Diaactivateur is only for diarich or dialight.
Which one were you using it with?
I think 6 is actually only for dia light (I stand to be corrected)

Using on diarich

Diaricich only covers/blends UP to 70% grey. Lifts 1.5 levels.
Might be time to move to maji or inoa

Greys are thru about 5% of hair so hoping for a good result with the correct vols
