Klonopin (clonazepam) is a long-acting benzodiazepine drug that can be detected in a person’s hair for four months or longer.
Hair drug tests can detect Klonopin for the longest period of time out of all drug tests. The timeline for Klonopin detection may vary according to various factors.

On Average, Klonopin can remain detectable in the hair for 90 to 120 days after last use.
Factors That Can Affect How Long Klonopin Stays In Hair
Hair drug testing methods will detect Klonopin for four months after last use, on average. This timeline can vary according to a number of factors.
Factors that can affect how long Klonopin stays in hair include:
- dose taken
- duration of use
- frequency of use
- method of use (e.g. snorting vs swallowing)
- metabolic rate

People with darker hair will sometimes have traces of drugs stay in their hair for longer. Cutting or styling your hair won’t affect how long Klonopin remains detectable in your hair.

Getting Off Klonopin For A Drug Test
Taking Klonopin for longer than a few weeks can cause the body to develop a tolerance to the drug and physical dependence.
Klonopin dependence can make it difficult to stop taking it long enough to get a negative drug test result, due to cravings and other uncomfortable withdrawal symptoms.
If you’ve been using Klonopin for more than a few weeks, do not try to stop taking it all at once. To get off Klonopin, you’ll need to taper your dosage with guidance from a doctor.
Overcoming Klonopin abuse may require inpatient or outpatient drug treatment.
