Going Medium Blonde

Hi!

My sister has decided she would like to go blonde. Her hair is almost dark brown. We think that a neutral medium blonde would probably look best on her. What level should her hair she be bleached to, and what toner to use after to achieve this? I think I''d like to go with the Wella line of toners, if anyone knows anything about these that would be great.

She also wants a few lighter blonde highlights around her face. Could the bleach on the strands she wants highlighted be left on a little longer, then tone her whole head with the same toner? Or would that end up a funky color?

For reference, this is the color she''d like to have.

Thanks a bunch for any help!!!

I wouldn't use that stuff from a box on her hair. If it's dark brown, it likely has red tones in it and would just turn orange. I would suggest she go to a salon.

When doing it at home, I don't personally use toner. If you do a good dye job, there's no need for it. People often use it as a fixer. To go lighter, you would have to use a dye with a green base to counter the orange that will come out, that's why I said boxed color isn't a good idea, because you don't know what base colors are in that and you likely won't get what you see on the box, especially when going from such a dark color.

Oh well, sounds like you know more about it than I do
I only speak from my own experience, (not a professional) and what I used to do was use a high lift color and developer, and choose a base to counter whatever yuckiness was coming out in my hair until I got what I wanted...no experience with bleaching then toning. Sorry!
