How Does Hair Drug Testing Work?

Hair drug testing is a method used to evaluate a longer history of potential drug use. The sample consists of 90-120 strands at least 1.5 inches long and must be collected directly from the testing subject’s scalp.

A collector cuts the sample close to the scalp and follows chain-of-custody procedures for specimen handling. Laboratory processing times can vary. A standard 1.5-inch scalp-hair sample commonly represents about 90 days of growth, though the detection window can vary by sample type and testing circumstances. Body hair testing may be used when scalp hair is unavailable, but it can provide a different, less precisely dated window.

When hair drug testing is paired with other types of drug testing, such as urine testing, you can get a more complete look at longer-term history and recent-use information. Hair testing is not designed to identify current impairment or drug use from only the most recent few days.

Benefits of hair drug testing include:

• A longer detection window than tests focused on recent use
• Laboratory processing times can vary
• Non-intrusive sample collection
• A scalp-hair sample that commonly represents approximately 90 days of history

Whether you’re an employer, attorney, government agency, or need a drug test for personal use, hair drug testing can fit situations where a longer detection window is required. The requesting organization may specify the specimen type, drug testing panels, collection procedure, or reporting requirements, so confirm those details and any deadline before scheduling.
