Hi, I also think you will get a better lift with the Wella high lift tints,
but if your client wants a really good lift without any scalp irritation
why not try a very gentle oil based scalp bleach there is one called proclere oil bleach
specially made for on the scalp bleaching only
from a level 5 it produces up and beyond (that very pale blonde )
without the burning or the itch ,
it is a blue Gel and comes with sachets for the degree of lightness you want
its so much less discomfort for the client than any high lift tints or powder bleaches
and you only ever use 6% with it
check it out its fab and fast too .
I get mine from salons direct ,
they also do proclere toners in a range of tones to match :hug: x
Wella also do a lovely Colour Fresh toner for blond bleached hair in 0/6 sliver ,
The hair first needs to be lightened past that baby chicken yellow blonde and up to that light creamy stage with the proclere oil bleach ,
(but don't go past the creamy stage or condition may be lost and toner will not hold ),
Then when the 0/6 toner is used after washing off the proclere oil bleach , it will give that white platinum blonde look
ps , always follow all manufactures instructions and always preform strand tests and skin tests before any bleach or tint procedure
