Breaking up a bad high lift

[Emzypops]

Hi Geeks,
So I have a new client who has been having a tint regrowth (high lift tint) for as long as she can remember. Base 4 60% Grey with a good 3 inch regrowth, hair is very porous but on strand test held fine. Colour is very warm would say a 9/3. She wants to stay lighter but break it up and iggtlt more natural, I was going to go in with 12/89 12% regrowth then some pieces bl 6% 7/73 1.9% and time after to try and shift the awful tones on her mid length and ends. Just wanted some advice on my choice as I don't want it to look uneven (wishy washy) thanks

Is there any chance you could go down to a 9%? As the root is looking really dry and try illumina range to break it up.

I could I was just worried about the lift as she has very course natural base of a 4. I'm not easily baffled but I don't want it to look awful thanks for reply
