I am thinking about using colour b4...?

I am only fifteen and admittedly dyed my hair light and dark brown, jet black, ginger, cosmic blue several times, bleached it twice, pink and purple already. I used to use straighteners every day, even when i wasn't going out, because stupidly, i cared what i looked like way too much. But now i haven't dyed my hair for at least five months and i barely straighten it. The last colour i dyed it was a permanent cosmic blue (which is black with a tint of blue if anyone was unaware) which seems to like to stick to my hair and it has faded a bit since then, it is currently a dark brownish colour. I have naturally blond hair and my roots have came through the colour I want my hair to be. I was just wondering how well would the product work on my hair and because I have bleached it, will it still work as well? thanks for every ones help:)
