Hair Test Basics :
This is the most expensive and the most accurate type of test.
Every time you introduce a toxins to your body, the blood carries it around in your veins depositing little bits of the toxins here and there throughout your body. As you can see from the diagram, toxins are deposited into the hair follicle and trapped permanently. As hair grows out, any drugs used are encased in the hair shaft, so the longer the hair, the longer back in the individual's drug history the laboratory can detect. Accredited hair drug testing laboratories, however, only use hair within about 1.5 inches of the scalp, and discard the rest. As human hair grows about 0.5 inch per month, hair drug test can show a 3 month history of drug use.
As hair grows slowly, hair drug test do not usually detect use of any drug within the past week and not significantly affected by brief periods of abstinence from drugs!
Hair test can sometimes be used to determine when use occured and if it has been discontinued. Drugs, such as opiates (codeine, morphine, heroin) lay down on the hair shaft very tightly and are shown not to migrate along the shaft, thus, if a long segment of hair is available one can draw some "relative" conclusions about when the use occurred. However cocaine, although very easy to detect, is able to migrate along the shaft; making it very difficult to determine when the drug was used and for how long.
Hair drug test tests positive a little more than twice as often as a urine test. In a recent study, out of 1823 paired hair and urine samples, 57 urine samples tested positive for drugs of abuse; while 124 hair samples from the same group tested positive.

Passing Solution :
Some people attempt to circumvent this through shaving their heads, but this isn't a way.
In the absence of the required amount of hair on the scalp, body hair can be used as an acceptable substitute!
So, the only way is to remove toxins from your hair. You can do that by washing your hair with a special cleanser.
We should mention here that there have been some allegations that ANY shampoo will cleanse the hair of toxin traces. Well, that is true, if you use a common shampoo long enough and often enough. We're talking about a lot of hair washes over a fairly long period of time here.... many days, weeks, or months, depending on the drug type and amount of usage. You usually have notice about a hair within test hours, or within just a few days!
We encourage you to get clean and to stay clean. That way, you don't need to worry about such tests. But, even for a lengthy period of time after you quit, depending on the type of test and the type of drug, you may want to consider keeping some of our self-test drug kits available. And, getting those toxins out of your system with one of our total body cleansers may help you get over the effects of drug usage much more quickly.
