Hi yes, im about a level 5 and I have had the 12/11 and it did the same as lianas,
as scottiedolly says it may go a bit too ashen especially if the colour
is lighter ,
I think if she wants white try bleach and toner
you could try an oil bleach gel made especially for the scalp so it doesnt itch or burn
its called Bluefrosting gel lotion made by Proclere
available from Salons direct or sallys
you can get single application boxes
they have a bottle of gel lotion and sachets of boosters in them
and all the instructions for different base colours are inside,
you only need 20 vol , and you will get really lovely high lift results
just bring it up to the stage of a creamy pale yellow colour
(just like the inside of a banana skin)
dont go beyond this colour or it will be too white and wont hold a toner when done
wash off towel dry
and then put on a toner whilst still damp
you can use one of the proclere toners that go with them for afterwards they also
have swatches for you to look at and come in shades of
platinum 352
sweet silver 353
blissfully blonde 355
intoxicating ivory 356
beautiful biege 357
or wella do a lovely toner that will take it to a cool light blonde
its called 0/6 violet / silver in colour fresh
non of the above toners cause grab which is great ,
just follow manufactures instructions :hug:
