Blonde hair lightener question?

i did have very dark almost black hair and i have it highlighted so now its brown with blondy ginger streak

basically i was given a garnier belle blonde pre lightener by a friend that purchased the wrong colour and id just like to know what would happen to my hair if i just slopped it all over would it all turn the same shade or would it still keep the differnt tones ? or should i do it in bits ?

Since your hair is already highlighted, the new color would vary for each shade currently in your hair.

All of your hair would be lighter. The hi-lites too. Don't do it too soon though. You've already bleached it once, give it at least two or three weeks to recover before trying to lighten it again. This would minimize any major damage to your hair.
