I know so many people asking but I’ve tried bleaching my usually highlighted very blonde hair. Highlights last done in January.
I used BBlonde by Jerome Russell and then a platinum toner to supposedly take out the brassiness. My hair is so bright but looks stupid as the top of my hair is WAY blonder than the rest. I really need a hairdresser 
Can I put a brown box dye in it to make it less bright? How do I avoid the top part (Mega blonde) being a different shade to the rest of my hair (it’s very long hair). Or is there some other toner I can use all over to bring it down?
Thank you for any input whatsoever
