I probably mean 'help with chemicals'. Where can you buy 880 Amonia from? Google keeps linking me to Amercian drugstores. I only need a small amount.

I also need some 6% Hydrogen Peroxide. Is this the same as the 20 volume stuff that people use to dye their hair (i.e. can I pinch some form my hairdresser?)

Can I just get all of this from a high street chemist without needing any info that says I'm not an extremist?
