So this was the results. (See end of post for the before pic)
I'm really happy with the colour. I love it even more now that i have some dark roots. I'm dreading doing my roots in the future as my hair here was already pre-lightened, new hair means I'll have to go through the awkward yellow cringe stage. & I'm also hoping to keep one centimetre of dark roots which i will cock up if i try to do it myself.
I was really impressed with the 'Bleach London' kit. The bleach does what it says on the really cool/hipster box & it really does lift the colour better than any of the 5000 home dye kits that I've used in the past. The hair reincarnation conditioner that comes in the box is literally the best thing ever. The toner removed the last of the yellow & left me with white sparkly hair. Yay. My hair actually felt in better condition after this bleaching session. WHAT KIND OF SORCERY IS THIS?!
Although I'm probably going to the Bleach salon in the future, for fifteen quid I'm chuffed with the Bleach London home dye kits.
This was the before pic (my child loves me really).
