What this test is
A hair drug test analyzes a sample of hair to detect certain drugs or their breakdown products that may have been used in the weeks before collection. It is often used when a longer window of detection is needed than urine or blood testing provides. The test does not measure impairment or current intoxication.
What it measures
- Amphetamines — Reflects possible exposure to stimulant drugs such as amphetamine or methamphetamine.
- Cocaine — Reflects possible exposure to cocaine or its breakdown products.
- Opiates — Reflects possible exposure to natural or semi-synthetic opioids such as morphine or codeine.
- Cannabinoids — Reflects possible exposure to cannabis or its metabolites.
- Phencyclidine — Reflects possible exposure to phencyclidine, also known as PCP.
- Benzodiazepines — Reflects possible exposure to sedative medications in this class.
- Barbiturates — Reflects possible exposure to sedative medications in this class.
- Methadone — Reflects possible exposure to methadone or its metabolites.
What the test involves
A trained collector cuts a small amount of hair, usually from the back of the head, close to the scalp. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order a hair drug test as part of a general health evaluation, pre-employment screening, or monitoring program. It is typically chosen when a longer detection window is useful compared with other sample types.
Preparation
Follow the collection lab's instructions about hair length, cleanliness, and any products to avoid before the appointment. Specific preparation steps can vary by lab, so confirm details with the collection site.
How results are reported
Results are reported as detected or not detected for each substance tested, and sometimes with an estimated level. Reference ranges and reporting formats vary by laboratory, so your results should be interpreted in the context of the lab that performed the test.

FAQ
Frequently asked questions
How far back can a hair drug test detect substance use?
Hair grows at a predictable rate, so a sample taken close to the scalp can generally reflect use over a period of several weeks to a few months. The exact window depends on hair length, growth rate, and the laboratory method used. Your collection lab can explain the expected detection window for your sample.
Can hair products affect the results?
Some hair treatments, such as bleaching or relaxing, may affect how much drug residue remains in the hair. Tell the collector about any recent chemical treatments so the lab can note it. The lab's instructions will explain what to avoid before collection.
Is a hair drug test the same as a urine or blood test?
No, each sample type has a different detection window and purpose. Hair testing generally looks for use over a longer past period, while urine and blood tests often reflect more recent use. A clinician can help you understand which type is appropriate for a given situation.
What should I do if I have questions about my results?
Contact the laboratory or the clinician who ordered the test to discuss what your results mean. Results are reported for each substance tested, and reference ranges vary by laboratory. Do not make health decisions based only on a lab report without talking with a qualified professional.
