I love blue hair, its got to be one of my favourite looks. Doing it myself actually, as soon as I have the money for some stronger hydrogen peroxide than is sold at pharmacies here over the counter (its limited to one 200ml bottle per sale of shitty 9% H2O2 and not only do I have really long hair, its naturally quite dark and 9% peroxide just doesn't bleach it well enough for the dye to take very well)
So going to buy some high-test stuff, and dilute it as needed, that way when/if I want strong H2O2 for the lab its available and I can simply add some to water to get the desired strength for bleaching my hair properly. Got some ultramarine blue dye. Will be just my sort of thing, I've had it blue before (so far, at different times, aside from my natural blackish-dark dark brown, I've had it yellow, red, pink, iridescent purple-black, various blues, platinum blonde, green, khaki and metallic silver colored)
That I can remember at least.
The thought of you with blue hair ren..god that really, really makes me wish it were wrapped around me because theres no two ways about it, you'd be fucking gorgeous. You are already, but even more so you'd be an absolute stunner (even more of one, that is to say:))
