Manic Panic Atomic Turquoise Hair Dye
my advice if you want your hair this colour is to bleach hair to the lightest blonde you can manage... platinum blonde... otherwise it won't come out as vibrant as it should, with the neon blue look..
but other than that i love it! it lasts too! i use about half a pot eachtime i dye it and i dont have long hair... each dye lasts about 15 washes id say, if you want to keep it a nice neon blue.... but even when it fades it looks kinda cool... a nice light blue ;D
