How do they do real hair drug testing im curious?

Testing hair for drugs is a more effective way of detecting drug use. If someone is taking drugs then a small amount of that drug will be incorporated into the hair as it grows. Once in the hair it will remain there for as long as that portion of the hair remains attached to you (and indeed even after it is removed eg by cutting or coming out during combing).

This means that it's much more difficult to cheat the system - most drugs can be flushed from your bloodstream quite quickly so that nothing shows up in your pee. But to cheat at a hair test you have to stop taking the drug several months before the test... or at least a few weeks if you have your hair cut really short (and that's ALL your hair!).

Many companies now use hair drug testing on their employees - not only is it more accurate, more difficult to cheat but it is also less of an invasion of personal privacy causing less embarassment

Shave it all off. They will never catch you then.

Im laughing at one response "shave it off" and then they wont catch you. Not true! Hair testing can be done with hair from any part of the body, and I hardly think you are going to shave your entire body!

It is much more sensitive that a urine test, so if you arent clean...dont bother!
