Will a white toner sort out my uneven platinum blonde hair?

Hi,

I want my hair a white blonde/platinum colour, my top half has gone the platinum I want but the bottom is slightly darker and it’s not even. Will a white toner sort this?

What can I do to even this out?

Please help,

If the top part of your hair is the colour you like and the bottom is the problem, then I suggest that you lighten the underneath again to the same level as the top, then tone it with a platinum/white toner to even it all out.

The back of the head is tricky to do yourself so I suggest you get someone who knows what they are doing and can see clearly where needs to be lightened and toned.
