Good luck with the bleaching, ugh!  I've done it
before, back in my youth, and it's always a bear
and a half to get right.  Just remember not to
blow-dry too often while it's bleached completely
white, since you've already damaged it pretty
severely in the process.  Excess stress will lead
to untameable mad-scientist hair.  *giggle*

Here's my newest oddly-hued duo, Seki and Sasaki!
