Blonde to purple - opinions please!

[kelly123]

Hi

I have a client in tomorrow who is going from a box dye blonde (hair I. Surprisingly good condition!)
She wants in purple with lighter purple slices.

I was thinking of using 55/66 all over but not sure what to out in the slices to give a lighter purple/violet colour that will be long lasting.

Any advice greatly appreciated.

I use Koleston.

I mixed up 10 koleston with a smidge of 0/66 to tone a full head bleach to violet it was yum x
