Hair follicle test is much more effective than just an ordinary test, the fact is that the hair can be washed with a shampoo or simply cut off just because an individual wants to escape the consequences of failing such test.
Drug residues can enter the hair follicle because blood is constantly supplied into the hair follicles to nourish them and make hair become replaceable, if there are some components of drugs in the blood, they will definitely reach hair shaft through the supply of blood to the follicles. Drug metabolites will always be produced regardless of whether the drugs are ingested snorted or smokes.
The principle of an hair follicle test is based on the same principle of hair test, the sample of hair can be taken from any part of the body, an hair follicle test sample should be between 100 to 120 strands of hair, and each must be at least 0.5 inch long, an hair that is 0.5 inch long is believed to have the capability of helping a tester to detect up to 30 days of prolong usage of drugs, if the hair is around 1.5 inches long then a prolonged usage of drugs for up to 90 days can be detected.
The principle behind the use of hair follicle test is that hair grows at least 0.5 inch a month and one can easily detect the actual period of time an individual has been using some drugs by simply measuring his or her hair.
When it comes to the detection of low level usage of a particular drug, hair follicle test is much more effective than ordinary hair test; it is also more effective when compared to urine and saliva drug tests. Hair follicle test can be used in detecting common drugs such as marijuana, Phencyclidine, Cocaine and Opiates. An hair follicle sample is taken by scrapping a little portion of the scalp of the head and that is where some metabolites of the drugs used are probably hiding, testing he hair as well as its base will give a more accurate result.
