Where are you using it - just on the roots, or all over?

If just on the roots it should be okay, but if all over it's too much.

How often is it ok to use 10 vol developer? Would every three weeks be ok?

My hair is in decent condition and I use it with a salon/professional dye to deposit/tone.

My hair is in pretty good condition.

Advice??
