What shade of blonde

[alimobile]

Hello.
What would you advise to achieve the colour on the right? Going from the colour on the left which is my clients current hair.
I use brands a.s.p, wella or majirel usually.
Many thanks

A.S.P I'd go with bleach for the lighter blonde and then use 8.035 + 9.003 + 3% for the warmer pieces.
I'd then tone the blonde with 2parts 10.0 + 2parts T32 + 1 part T21S

If you were to use Wella I'd go with blondor , then CT 9/36 + 8/38 1.9%
Toner I'd do colour touch 3parts 10/0 + 1part 10/6 + 1.9%

Thank you very much. Would you drag the colour straight through from the dark roots onto the already lightened bits or would it be best to shade down on those bits? They are previously bleached but hair isn't very porous as it's not been done for a while .
