That said, I have been dyeing my hair pretty much every shade under the sun for over a decade, beginning with The Great Sun-In Fluorescent Orange Streak Debacle aged 12/13. I've tried every brand of box dye in the UK drugstore and many of the mixable potions available at Sally's too, and these Kao Bubble hair dyes blow them all away. They're so effortless that I'd confidently recommend them to first-timers, and personally, I can and have dyed my hair evenly with these on a tipsy getting! things! done! rampage, without a mirror, while cleaning the kitchen and organising aaaaaall the DVDs by genre.
Black Tea Brown is one of the new shades released in Autumn 2011. Continuity with the old line-up is provided by the derpy porno-faces.
I originally wanted to try Natural Black because my many layers of russet-through-burgundy were peeking through the black Schwarzkopf Live I'd layered over them back in London, but that shade was sold out in every drugstore in Hong Kong. Black Tea Brown is the next-darkest shade in the line so I snatched up the last box.
artificial light, no flash (two months ago, my hair was inky box-dye BLACK)
Inside the box: everything you need to follow the instructions here.
After mixing, one pump.
I leave the dye on for 20 minutes when going darker, and 30 minutes when going lighter.
Half an hour after opening the box, we're done.
A final rave: ZERO residue left on towels over the next few hair washes, and I got to experiment on plenty of pristine white Beijing hotel towels.
HK$78 each from adambeauty here (though he doesn't seem to have the new shades yet).
The Kao sub-brand is called "Liese", "Prettia" or "Liese Prettia" in different Asian markets -- the products are the same so just make sure you have the right shade, and ignore the name on the box.
