How far back can a hair drug test detect?

Most companies go back 3 months, but some go back 6 months. A good lab can detect drugs in your hair shaft all the way to the bottom, So drugs stay in and become part of your hair shaft till it is cut out. When you figure your hair grows and inch every 4-6 weeks( normal ) If you did drugs three months ago and your hair is three inches long you would have to cut your hair to an two inches from the scalp. Hope you understand this.......Flo

As old as the hair is. If you shave your head, then use drugs and let your hair grow. That drug use will be there as long as you have that hair uncut.

Hair tests can go back as far as 6 months. Don't try shaving your head because hair from your arm pit,legs,or pubic will work. This kind of test can tell how frequent and what drug flavor is your choice.

They can go back as far as your hair is long. The minute you do drugs it can be detected in your hair. The only way around it is to shave your head and be drug free. Hair drug test will detect:



Cocaine (cocaine %26amp; benzoylecgonine)



Marijuana(THC)



Opiates (Codeine, Morphine %26amp; 6-monacteyl morphine)



Methamphetamine (Meth and Ecstasy)



Amphetamine



Phencyclidine (PCP)

In theory even if you cut your hair and arm and leg and all body hair the substances could still show up in growth for up to 30 days after you cut the hair for THC, 3-4 days for meth and coke and other substacnces as they are still in your body and therefore should show up in your hair. I would imagine you may need to stop using for 30 days and cut and allow regrowth to be 100% sure but all the other answers seem pretty accurate too. I just tend to think in terms of extremes and worse case scenarios, kind of like Puddleglum you know.
