Please do not call it "bleach", it is not chlorine, it is hydrogen peroxide.
Someone coming across this thread may be confused by this. I have no idea what would happen if chlorine bleach and hydrochloric acid were mixed.

Look for clear hair bleach. I think it's around 12% (40 deg. Baume?);

you out.
I got mine from the local Sally Beauty Supply.
In this part of the US they seem to show up
near WalMarts.
