Did you pass or fail? How long does a hair drug test take for results?


Did you pass or fail? This question has haunted us since childhood, However, as adults, the stakes are much higher, especially when facing a Hair Follicle Test. This test, often required by potential employers, can significantly impact your career prospects. It is one of the most critical assessments for many adults today, as a negative result can stand between you and your dream job.

So what is hair follicle drug test? Why is it done

Today, various tests are available that can help detect drug use by individuals. Two tests that are non-invasive and easy to administer are the urine tests and hair follicle tests. A urine test detects recent consumption of drugs, say within the last few days, and is often used as part of crime investigation, addiction treatment facilities etc. However, a follicle test will not work if you want to assess drug consumption in the last few days because it takes approximately seven days for the drugs to appear in the hair follicles after consumption. The test can detect marijuana, cocaine, opiates, and other drugs easily, and the traces of these drugs remain for a longer duration, say up to 90 days or more, based on the intensity of usage. For example, if you consume weed it can be detected in hair follicles for up to 90 days after one-time or moderate use, while heavy use can be detected for up to six months. This method gives you a better picture of drug consumption by the individual in the last few months and is preferred by employers while screening new prospective employees.

How long does a hair drug test take for results?

There are two ways to undergo the test. You can do it in a lab or using a test kit. The sample is then sealed and mailed to the lab. The initial screening is called the ELISA test – Enzyme-Linked Immunosorbent Assay. The results from the initial screen are provided within 24-48 hours if the test results are negative and no drugs are detected. On detection of drugs in the initial screening, the sample is further sent for a confirmatory test. The test uses gas chromatography/mass spectrometry (GC/MS) or liquid chromatography/mass spectrometry (LC/MS) technologies and provides highly accurate results. It takes an additional 72 hours for the results to be delivered.

How accurate are the results

The collected hair samples are first washed to remove any externally deposited drugs. It is then tested for environmental exposure like passive smoking, etc. because these can lead to a false positive test result. Studies say that the confirmatory test – the GC/MS test – can detect as many as 17 different drugs. However, what it cannot confirm is the date during which they were consumed.

While the hair follicle test is considered to be fairly accurate there are a few factors that can affect the accuracy. Cleansing the hair and scalp before the test, use of different hair care products, hair colors etc. The insight from this is that there are detox products available n the market that can help you pass a hair drug testing and remove all traces of drug residue from their hair.

A guide to choose the right hair detox products to pass the drug test

The market is saturated with hair detox shampoos and scalp scrubs that promise an escape from the drug test. However, not all of them are fully effective. It is better to remain cautious of unknown brands without proven success. Human hair has three layers – the cuticle, cortex and the medulla. The drug residue or metabolites find their way into the cortex. A good detox shampoo penetrates beyond the hair’s protective cuticle to reach the cortex and dissolve the drug metabolites from the cortex.  They contain propylene glycol and surfactants, which aid in penetrating the hair cuticle and dissolving the embedded metabolites. It is a complex process and only a few products can achieve this. Hence, it is crucial to identify an expert in this field and select the right products. Aloe Toxin Rid Shampoo, Zydot Ultra Clean, Macujo Aloe Rid, etc., are a few popular and effective shampoos available in the market. Over and above these people also opt for home remedies for detoxification, for example, washing hair with vinegar and baking soda, etc.
