THC, or tetrahydrocannabinol, is the psychoactive compound in cannabis that produces the "high" feeling. When you consume THC, it is absorbed into your bloodstream and distributed throughout your body, including your hair. Hair drug tests can detect THC for up to 90 days after use, making them a common method for employers and law enforcement to test for recent cannabis use.
The amount of time that THC stays in your hair depends on a number of factors, including the amount of THC you consume, the frequency of your use, and your hair's growth rate. In general, the more THC you consume and the more frequently you use it, the longer it will stay in your hair. People with faster-growing hair will also have shorter detection windows than those with slower-growing hair.
While hair drug tests can be a useful tool for detecting recent cannabis use, it is important to note that they are not always accurate. A number of factors can affect the results of a hair drug test, including the type of test that is used, the skill of the person performing the test, and the presence of other drugs or chemicals in the hair. As a result, it is important to interpret the results of a hair drug test carefully.
How Long Does THC Stay in Your Hair?
THC detection window varies.
- Up to 90 days.
- Depends on usage and hair growth.
- Heavier use, longer detection.
- Faster growth, shorter detection.
- Hair drug tests may be inaccurate.
- Factors affect test results.
- Interpret results carefully.
- Consult a professional if needed.
If you have concerns about THC detection in your hair, it is important to consult with a medical professional or drug testing expert. They can provide you with more information about the factors that affect THC detection and help you interpret your test results.
Up to 90 days.
The detection window for THC in hair can be up to 90 days, but this is just a general guideline. The actual amount of time that THC stays in your hair depends on a number of factors, including the amount of THC you consume, the frequency of your use, and your hair's growth rate.
- Single use: If you only use THC once or twice, it is unlikely that it will be detectable in your hair. However, if you use THC more frequently, it is more likely to accumulate in your hair and be detectable for a longer period of time.
- Amount of THC: The amount of THC that you consume also affects how long it will stay in your hair. The more THC you consume, the longer it will be detectable.
- Hair growth rate: People with faster-growing hair will have shorter detection windows than those with slower-growing hair. This is because the THC is diluted as your hair grows.
- Other factors: A number of other factors can also affect how long THC stays in your hair, including your age, weight, and metabolism.

A number of factors can affect the results of a hair drug test, including the type of test that is used, the skill of the person performing the test, and the presence of other drugs or chemicals in the hair. As a result, it is important to interpret the results of a hair drug test carefully.
Depends on usage and hair growth.
The amount of THC that you consume and the frequency of your use are two of the most important factors that affect how long THC will stay in your hair. The more THC you consume and the more frequently you use it, the longer it will be detectable.
For example, if you only use THC once or twice, it is unlikely that it will be detectable in your hair. However, if you use THC daily or multiple times per week, it is more likely to accumulate in your hair and be detectable for a longer period of time.
Your hair's growth rate also plays a role in how long THC will stay in your hair. THC is deposited in the hair shaft as it grows, so people with faster-growing hair will have shorter detection windows than those with slower-growing hair. This is because the THC is diluted as the hair grows.
As a general rule, THC is detectable in hair for up to 90 days. However, this is just a general guideline. The actual amount of time that THC stays in your hair will vary depending on your individual usage patterns and hair growth rate.

The amount of THC that you consume is one of the most important factors that affects how long it will stay in your hair. The more THC you consume, the longer it will be detectable.
- Single use: If you only use THC once or twice, it is unlikely that it will be detectable in your hair. However, if you use THC more frequently, it is more likely to accumulate in your hair and be detectable for a longer period of time.
- Daily use: If you use THC daily or multiple times per week, it is likely that it will be detectable in your hair for up to 90 days.
- Heavy use: If you use THC heavily, it is possible that it will be detectable in your hair for even longer than 90 days. This is because THC can accumulate in the hair shaft and be released slowly over time.
- Edibles and concentrates: Consuming THC in edibles or concentrates can also lead to longer detection times. This is because these forms of THC are more potent and can result in higher levels of THC in the hair.
It is important to note that hair drug tests are not always accurate. A number of factors can affect the results of a hair drug test, including the type of test that is used, the skill of the person performing the test, and the presence of other drugs or chemicals in the hair. As a result, it is important to interpret the results of a hair drug test carefully.
Faster growth, shorter detection.
Your hair's growth rate also plays a role in how long THC will stay in your hair. THC is deposited in the hair shaft as it grows, so people with faster-growing hair will have shorter detection windows than those with slower-growing hair. This is because the THC is diluted as the hair grows.
- Slow growth: If you have slow-growing hair, THC will stay in your hair for a longer period of time. This is because the THC has more time to accumulate in the hair shaft.
- Fast growth: If you have fast-growing hair, THC will be diluted more quickly as the hair grows. This means that it will be detectable in your hair for a shorter period of time.
- Haircuts: Getting regular haircuts can also help to shorten the detection window for THC in your hair. This is because the THC is removed from the hair shaft when it is cut off.
- Hair treatments: Some hair treatments, such as bleaching and dyeing, can also remove THC from the hair shaft. However, it is important to note that these treatments can also damage your hair, so it is important to use them sparingly.

Hair drug tests may be inaccurate.
Hair drug tests are not always accurate. A number of factors can affect the results of a hair drug test, including the type of test that is used, the skill of the person performing the test, and the presence of other drugs or chemicals in the hair.
- Type of test: There are two main types of hair drug tests: immunoassays and mass spectrometry. Immunoassays are less expensive and more widely available, but they are also more prone to false positives. Mass spectrometry is more expensive and less widely available, but it is also more accurate.
- Skill of the person performing the test: The skill of the person performing the hair drug test can also affect the accuracy of the results. If the test is not performed correctly, it can lead to false positives or false negatives.
- Presence of other drugs or chemicals: The presence of other drugs or chemicals in the hair can also interfere with the results of a hair drug test. For example, some hair care products contain ingredients that can cross-react with THC and produce a false positive result.
- Environmental factors: Environmental factors, such as exposure to secondhand smoke or marijuana smoke, can also lead to false positive results on a hair drug test.
It is important to note that hair drug tests are not always reliable. If you have concerns about the accuracy of a hair drug test, you should talk to your doctor or a drug testing expert.
