Hair drug test

This is the most accurate type of test, and it allows detection for weeks and months after use, depending on the type of drug and usage length and amount. When first invented, large clumps of hair were collected, and this raised legitimate gripes from those being tested. Methods have improved, and smaller amounts are now taken that rarely show. Hair strands are examined under microscope before and after being chemically treated, to determine how long ago the drug was used, the type of drug, and the duration of use. Keep in mind that the human hair grows about 1/2 inch per month, which enables this type of determination to be made. As the methods for collecting samples and testing have improved, the costs to the employer have gone down and the use of this type of test has risen, particularly for pre-employment screening.

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.
