Where I get my hair cut (unisex salon) I asked the lady doing my hair if
they could buy some high-strength H2O2 for me. She said that they don't use
it any more, it comes pre-mixed with the other stuff they use, and was I
into bomb-making. She was joking, of course. You don't need a license to buy
it in the UK, of course. I suppose if I ordered it from a chemical supplier
together with acetone, the supplier might be suspicious and report me to the
police. The (failed) bombers recently convicted here used H2O2 bought from a
hairdessers' supplier.
