How far back can the hair follicle test go to detect drug use?
The hair follicle drug test, when using the standard 1.5 inches of hair, can detect previous drug use up to 3 months. If a longer piece of hair is selected, the drug test results can go back much further (in fact, years further) to detect drug use.

It's suspected that this is the rain Britney Spears shaved her head: a drug test related to her divorce. Hey ads are now held in trust, and managed by her family.
I have absolutely no doubt that ((they)) molested her, and it destroyed her mind.

that is because they specifically measure out 3 months worth of hair for the test to be 'fair' to everyone. They can test back as long as your hair is long, but people with short haircuts generally don't have anything longer than pubic/ arm pit hair.

Or perhaps someone who hasn't cut their hair in decades.

Hair tests don't go back decades. Research the topic.
