On a hair follicle, drugs will show up after 90 days of using the drug. However, it typically depends on the type of drug and the frequency of usage.

Will a hair drug test be able to detect the difference between 20mgs of Adderall XR and 30mgs of generic adderall taken twice daily?

NO, in short hair test only test for the drugs that are in hair follicle, they do not test the quantity of the drug in the follicle. so the hair drug test will show you as being positive for amphetamines, but they can't determine how much amphetamines was used, so going from 20's to 30's will show up no different on a hair test.
