Hair colouring for medium blonde hair??

I have light blonde/medium blonde hair, and light brown hair in my under-layers. I want to try a Shades and Toners Wash In/Out but will it turn my hair a funny colour or will it work properly? I want to use light ash blonde.

stay away from the ash! Blonde hair picks up the green in the ash and will make you look like a swamp monster! (Trust me, Ive done it to myself!) Keep with the warms, not the cool tones.

to be honest these will not do a lot on your hair at all, they will work on hair bleached to the pale yellow stage but yours doesn't sound like it is and in fact you have brown in your hair aswell, the word TONER means to tone down "brassy" or "bright" bleached hair- NOT FOR CHANGING HAIRCOLOUR!
