Alcohol hair tests are an increasingly common method of testing for alcohol consumption over an extended period. The tests are highly accurate and can detect alcohol consumption over several months, compared to the shorter timeframe of blood and urine tests. The tests are often used to determine whether someone has been drinking less or more than before, or if they have abstained from alcohol for a long period. They can also be used to detect binge drinking or alcohol abuse. The tests are typically carried out by taking a small hair sample from the head, although samples may also be taken from chest, armpit, or groin hair. The hair sample is then analysed in a laboratory to determine the presence and quantity of alcohol. While the tests are considered reliable, there are examples of false positives and negatives, and cosmetic hair treatments can interfere with results.

What You'll Learn
The vinegar rinse method
To perform the vinegar rinse method, follow these steps:
- Before bathing, apply vinegar to your hair and scalp. This will help smoothen the hair cuticles and remove any drug residue.
- Use a shampoo, preferably a detox shampoo like Old Style Aloe Toxin Rid or Zydot Ultra Clean, to wash off your hair. Shampoos with baking soda or salicylic acid may also be used.
- Apply conditioner to improve hair health.
- Repeat this process multiple times to reduce the concentration of drugs in your hair and improve test results.
- On the final day before the test, it is recommended to use Zydot Ultra Clean shampoo for the best results.
- If desired, you can also dye your hair back to its original color after the process.
It is important to note that while the vinegar rinse method has been reported to be successful by some individuals, there is no guarantee of passing a hair follicle test. Additionally, frequent use of vinegar may damage the hair, causing it to become dry and frizzy. Therefore, it is essential to use a good moisturizer after the process.

Detergents and acne medications
It is important to note that hair follicle tests can detect alcohol consumption for up to three months. The best way to pass a hair follicle test for alcohol is to abstain from drinking for at least three months before the test.
If you are unable to do this, there are some home remedies that people claim can help you pass a hair follicle test, but these are not guaranteed to work. One such method involves using detergents and acne medications. However, applying these products to the scalp can dry out the skin and cause irritation, so use them with caution. If you show up to your test with a visibly irritated scalp, the tester may suspect that you are trying to beat the test.
- Soak your hair with a salicylic acid acne treatment containing 2% salicylic acid, such as liquid Noxzema. Pour slowly and allow the liquid to soak into your hair. Leave the acne treatment in your hair for about 30 minutes.
- Work one capful of liquid detergent, such as Tide, through your hair thoroughly. Do not rinse out the acne treatment before doing this. Be careful, as Tide is quite abrasive and could damage your scalp.
- Add a dash of water to one scoop of powder detergent to make a paste. Scrub this onto your scalp and hair, concentrating on the back of your head, as samples are most commonly taken from this area.
- Let the paste sit for about 20-30 minutes.
- Rinse all the products out of your hair. Do not wash or condition your hair after rinsing.
- Optionally, dye your hair using a standard store-bought dying kit. Rinse well and use the conditioner that usually comes with the hair colour kit.
Again, it is important to note that this method may not work, and even if it does, it is only a temporary solution. The only reliable way to pass a hair follicle test is to abstain from the substance in question for an extended period before the test.

Shaving your hair off
If you shave your head, the tester may take a sample of body hair instead, such as chest hair, armpit hair, or groin hair. However, shaving your head may give you enough time to abstain from alcohol so that any future test is negative. A hair follicle test requires at least a 3-centimetre sample, which equates to around three months of growth. Therefore, shaving your head can give you a three-month window to avoid drinking.
It is worth noting that shaving your head is not a guaranteed way to pass a hair follicle test. The test can still be conducted with a very small sample, and even a few strands of hair could be enough to detect alcohol consumption.
Additionally, shaving your head may be seen as a drastic measure that could arouse suspicion. It may be more practical to cut your hair short, rather than shaving it all off, to reduce the time frame of alcohol detection without attracting attention.

Cosmetic hair treatments
Alcohol hair tests are a reliable method to determine alcohol consumption over a long period. These tests are often used to detect alcohol abuse or to prove abstinence. While they are accurate, there are some factors that can affect the results. Cosmetic hair treatments, for example, can interfere with the results of hair follicle alcohol tests. Here are some things to consider:
Bleaching
Bleaching your hair can interfere with the test results and may even give a false negative. This is because bleaching strips the hair, removing any evidence of alcohol use. However, testing professionals are often aware of this tactic and may request a body hair sample instead.
Perming
Perming your hair can also impact the results of a hair follicle alcohol test. The chemicals used in the perming process can alter the hair's structure and potentially break down any alcohol markers. This could lead to a false negative result.
Hair Sprays and Gels
Alcohol-based cosmetic products, such as hair sprays and gels, can cause a positive result on a hair follicle alcohol test. These products can be absorbed by the hair follicle, leading to a false positive. It is recommended to avoid using these products before a hair follicle test and to wash your hair to remove any residual product.
Other Treatments
Other cosmetic hair treatments, such as straightening or using hair creams, may also impact the results of a hair follicle alcohol test. It is important to disclose any hair treatments or products used to the testing laboratory to ensure accurate results.
It is worth noting that while cosmetic hair treatments can interfere with the results, the hair follicle alcohol test is still considered extremely difficult to deceive. Combining the hair test with other methods, such as blood or urine tests, can also help ensure the most accurate results.

False positives and negatives
Cosmetic hair treatments and products, such as bleaching, perming, and alcohol-containing hair products, can lead to false positives. Additionally, exposure to second-hand alcohol smoke or using "cleansing" products that claim to remove alcohol or drug traces from hair can also contribute to false positives. Furthermore, prescription medications and specific foods, like poppy seeds, may contain compounds that can be mistaken for alcohol metabolites, resulting in false positives.
False negatives can occur if the test is conducted within 5-7 days of consuming a significant amount of alcohol. In this case, the alcohol may not have been incorporated into the hair strand yet, resulting in a false negative.
It is important to note that hair follicle alcohol tests do not test the outer part of the hair but the inner core, making it challenging to alter the results. While shaving your head may delay the test, it will likely arouse suspicion. Detox kits and shampoos are also ineffective as they only treat the hair's exterior, and most employers will request the test again.

Frequently asked questions
A hair follicle test for alcohol is a method of testing for alcohol consumption over an extended period, typically 3 months, but sometimes up to 6 months or even years. The test involves taking a small hair sample, usually from the head, which is then examined for the presence of ethanol or ethyl glucuronide (EtG), a direct marker of alcohol consumption.
The best way to pass a hair follicle test for alcohol is to abstain from consuming alcohol for several months beforehand. As alcohol is broken down and absorbed into the hair follicle, evidence of alcohol use can be detected for several months. If attempting to pass the test without abstaining from alcohol, some sources suggest using home remedies such as vinegar rinses, salicylic acid, and detergent, although these methods are not guaranteed to work and may irritate the scalp.
Hair follicle tests for alcohol are considered highly accurate and can provide a more detailed picture of alcohol consumption over time compared to blood, urine, or breath tests. However, they are not foolproof and can produce false positives or negatives. Factors such as cosmetic hair treatments, hair preservation, and usage of alcohol-containing products can impact the accuracy of the test results.
