Bleaching my hair part 2

Ok so in my last post I'd managed to get my hair to the pale yellow stage. The roots were almost white blonde, with the underside very pale yellow and the mid lengths of the top layer a darker yellow. So very patchy all over. Now when I did this bleaching and toning I'd left it a couple of weeks so I had to re do my roots but they came out fine, same as before. I used all the same bleachibg products and measurements as I did in part 1. After the bleaching the underside was as light as the roots so nearly there, but once again the top mid lengths were just a bit darker, you couldn't tell properly inside but in bright light it was quite obvious so I thought toning might help. I used Loreal Luocolour P01,with 25% developer. And this worked amazingly all over. I think it said to leave it on for 20 minutes, I left it for just a bit longer, maybe half an hour as I'd read from other reviews it can give a lilac hue to your hair as it is a purple based toner. The roots came out a platinum colour with a tiny but of purple, and the mid lengths went pure blonde, no yellow. Once again it was a tiny bit darker but still light blonde. So because I'd got it all very light I thought I'd go ahead and try the all over pastel dye. I had Crazy Colour in Lilac and I diluted it with a looooooot of white conditioner. Too much. I used the full bottle of dye and god knows how much conditioner. The roots once again turned a nice colour but it didn't affect the midsection. Gutted! Here's a picture of my roots, I really liked this.

So the overall conclusion is I think it needs one more bleach and tone, primarily on the dastardly middle part! The Loreal Luocolour is amazing, I would definitely recommend it for completely taking away brassy or yellow tones. I've also been using Provoke Touch of Silver which keeps the roots a great colour. The purple has pretty much all washed out and I've been left with a slight green tinge which is just unfortunately how the purple fades.

Hopefully just one more post to go till I get it a nice white blonde everywhere! Here's how it looks just now.
