Defeating Hair Follicle Drug Test
A Drug Test is the process of determining the presence or absence of drug residues inside a person. This in turn is an indicator of the drug consumption habits of the individual. All government employees and many private employees are made to undergo these drug tests. The issue of drug tests is debatable. It does a tight rope walk between the privacy of employees and the concern of the employers to maintain a healthy work place free from the vices of accidents, conflict, under performance, absenteeism and the like.
The main types of drug testing are blood drug test, urine test, saliva test, sweat analysis / test and hair test. Hair follicle drug tests are becoming increasingly popular with employers. The reason is that this test can trace a person’s (in this case the employee) drug consumption habits for a greater period than the traditional urine drug testing.
The hair follicle is a part of the skin that supports the hair that grows on its surface. The site of the hair follicle marks the point where old cells are packed together in order to support hair growth. A sebaceous gland and a minute sebum producing gland are also attached to the follicle. The sebum producing gland is absent in body parts like lips, palms and soles of the feet.
Hair follicle tests are expensive than other tests and are generally used by the government to test military personnel. These tests usually check for drugs like cocaine, marijuana, methamphetamine, PCP or phencyclidines and opiates. Most hair follicle tests will determine consumption history of 90 days prior to the test.
Drug residues accumulate inside the core of the hair. The trick then is to remove these accumulated residues. This is done by washing hair by special shampoo and then conditioning them. The hair drug shampoo contains a chemical known as the masking agent. When it comes in contact with the accumulated residue it covers the residue. The testing machine is therefore not able to detect the residue. The conditioner is then applied to get the hair back in their original hairstyle. However, it is strongly recommended that the shampoo be applied under professional guidance.
