Although similar, there are a few differences. Here are the facts: 1. If head hair it too short, body hair can be used. Although there is no released research or tests, it is suspected that the body hair test can be detected much further back, as far back as a year.

Children, teenagers, and young adults typically have faster hair growth rates than older adults. This can alter the window of detection due to growth rate, growth cycle, and length of hair.

However, hair does not keep growing indefinitely. After a growth period called the anagen phase , the follicle goes into a transient period catagen phase in which it begins to shut down. Eventually, the follicle degenerates and the hair falls out telogen phase [4]. The cycle begins again, and a new hair shaft is produced. These phases are ongoing and do not necessarily align — different strands of hair may be in different growth phases.

Head hair grows faster than body hair and may grow for several years before entering the catagen transient phase. A time-course of drug use can be determined by performing a segmental analysis [5]. Hair closest to the head represents the most recent drug use.
