No, exposure to the smoke of marijuana does not stay in the hair forever, but duration does depend on the frequency and severity of exposure and frequency of washing hair.
What does happen though is, if a person smokes marijuana there are traces of it that reaches the follicles and grows into the hair. A hair sample can be taken from the person and tested and can prove that he/she smoked marijuana.
it will stay in there for about 2 years
Forever.
EVERYTHING stays on a hair test. Forever.

well...it never grows in you hair, but if you mean how long can marijuana be detected in the body... its about 3-30days depending on your metabolism
The scent of marijuana smoke stays in someone's hair for over 2 hours. The scent can make someone who was smoking in secret to be identified.
No.
Forever!
About 15 days.
60-90 days per use. It stays in the fat and hair cells, so you could pass a urine test after 90 days but a hair test will show it.
It can stay your system for up to 30 days after your last smoke.
Not necessarily, however it does increase your high.
