Beauty supply stores sell quarts of liquid H2O2 in 20, 30, and 
40 'volume' strengths. These correspond to 6%, 9%, and 12% H2O2 
respectively.

'Sally Beauty Supply' (and probably others) sell to the general 
public. No beautician license is required to buy it there. Some 
supply stores will sell their products only to licensed 
professionals.
