A hair follicle test is used to detect the presence of various types of drugs in the body, including opiates, cannabinoids, cocaine, amphetamines, and PCP. This type of test is the best method of finding evidence of long-term drug use, since the hair grows very slowly. Testers usually take a sample that represents 90 days of growth. New employees who are required to take a hair follicle test may worry that a past experience with drugs will cost them their job. The following are some methods people use to try and pass a drug test.
Cease Using Drugs
Since drugs can stay in hair for such a long time, it’s necessary to plan far in advance in order to be able to provide a clean sample. In order to pass a hair follicle test, a person should be drug-free for at least 100 days. Marijuana users need to wait even longer, between 110 and 140 days, depending on how much and how often they use. Most people do not find this to be an effective method.
Shave The Head
Some people reason that shaving their hair completely will make a hair follicle drug test impossible. However, the hair on the head is not the only eligible hair, so testers will usually sample body hair if head hair is not available. This turns out to be a much riskier option since body hair grows far more slowly and the same sample size may actually reveal a year’s history of drug use.
Bleach The Hair
Some people use hair bleach as a way to cleanse the hair of toxins. It’s true that bleach does remove some traces of drug use from hair follicles, but it isn’t 100% effective. The downside of using bleach, especially using it repeatedly, is that it damages the hair badly.
Use A Detox Shampoo
According to Quickfix-Ultrapure, detox shampoos offer a quicker solution to cleaning the hair than 100 days of abstinence. These shampoos are designed to strip the hair of metabolites, and they can be used 3-5 days before a drug test. While these products don’t offer a 100% guarantee, they are often the best option available.
