A hair drug test uses an average of 40 mg of human hair. Since April of 2004, there has been a growing need for a way to produce a false negative reading during such a hair drug test. A number of possible suggestions have appeared on the Internet. The manufacturers of one product have described their particular product as “a body wash for body hair and scalp hair. “ They have promised to get rid of all the toxic substances in each of the 50 to 70 strands of hair that will need to be examined during the established testing process.One can not provide a single answer to the question “How does a hair follicle test work?” That is because there are currently two different ways for seeking results from a hair drug test. One involves ultra-sensitive gas chromatography and mass spectrometry (GC/MS). The other method involves use of a radioimmunoassay.

The employer who plans to hire a service that can conduct a hair drug test should know that the radioimmunoassay (RIA) offers two advantages over GC/MS. The RIA can detect 10 to 15 times as many drugs as the GC/MS. The RIA results also offer more information. They will tell an employer the exact quantity of the detected drug that existed in the blood stream of the test subject.

Employers developed a greater interest in the hair drug test after April of 2004. During that month, the government said that Federal agencies could choose the nature of the specimen that would be used for any drug test. Prior to that announcement, the Federal agencies had all relied on the urine drug test.

The 2004 announcement gave employers in Federal agencies the ability to test for drug use with hair, saliva, sweat or urine samples. The hair drug test has been shown to be especially well-suited for use in pre-employment drug testing and in random drug testing.  The hair drug test can pick up evidence of drug use as much as 90 days after the test subject has enjoyed the high from an illegal substance.

The increased use of the hair drug test has initiated a call for better ways to avoid a positive result from such a test. In order to answer that call, some manufacturers now offer drug users added information on how drug use can show up in a person’s hair. That information highlights the growth of hair.

Growth requires energy. Growth also requires the availability of important nutrients, notably protein. The blood provides body parts, such as the hair, with energy and nutrients. The blood travels to the hair follicle. Toxins in the blood can therefore enter the hair follicle.

The question then for a drug user who wants to beat a hair drug test is this: “How can I hide the presence of toxic substances in my hair follicles?” One possible answer is Zydot, a special shampoo. Zydot contains one substance that exposes the inner portion of the hair follicle. Zydot contains a second substance that penetrates into the hair and washes out any toxins that have become lodged in the hair follicle.

Zydot contains a third substance that does not assist with the removal of the toxic substances. The conditioners in Zydot allow the manufacturer to promise an absence of damage to the hair during the thorough cleaning process.
