Does marijuana stay in the root of the hair follicle for 6 months, or does it get pushed out by the new hair growing in?

In brief: Long time

Thc is stored in fat cells which serve as a reservoir and release it slowly into the bloodstream and from there into hair follicles.
For a long time user, the "reservoir" can be quite full and so may feed follicles at 6 mo and longer. The new hair growing out takes some follicle thc with it as new thc is being fed in.
