As I have said on several occasions before it is absolutely NOT
necessary to use bomb-quality peroxide. 12%/40 vol, which is the
standard hairdresser volume or 18%/60 vol will both work fine and are
what I have used on thousands of ivories over many years. Perhaps
you are confusing vols with percentages.
