I bleached my hair to a pale yellow/ orange, sectioned it into chunks, dyed chunks alternately with Directions 'Turquoise' and 'Midnight Blue' and then conditioned the bejesus out of it. You can't really tell there are two separate dyes in there unless you're really looking - I think that's thanks to my haphazard dying style! I love the different shades in it, ranging from pale minty blue to almost neon turquoise - bit I think that's more thanks to how some parts were paler than others after bleaching.
I LOVE IT. Aint it just the prettiest colour eveeeer?! It's like the crown jewels mated with the coral reef or something equally nonsensical and magical. Despite breaking my vow not to bleach/ damage my hair until it was much longer, I think it was worth it! Next time, though, I think I'll go for Special Effects 'Fishbowl' - a paler, more aqua shade.
Directions dyes can be bought from eBay for around £2.99 - £3.50. The lippy I'm wearing is Barry M 52.
