If you are looking for information on how to pass a hair drug test, then you are not alone Passdrugtests.net . This is becoming an increasingly popular method of drug test due to the fact that hair drug testing can date drug usage back farther than traditional urine tests can. The most common types of drugs that a hair drug test will look for include marijuana, methamphetamines, opiates, cocaine, and PCP; however, it can also be used to detect traces of nicotine and alcohol abuse.

Before you begin to learn how to pass a hair drug test, you will first need to learn how it works. Your hair grows at a rate of approximately ½ inch a month. Its growth is fueled by small blood vessels, called capillaries, located underneath the scalp. When you ingest a drug, drug metabolites are dispersed into your blood stream. As it circulates through your body, these metabolites are deposited into the shaft of your hair.

If you have only taken drugs in the last 2-3 days, then you may not need to worry about how to pass a hair drug test. It takes between 3-5 days for drug metabolites to appear in your hair. When you are given a hair drug test, you will be screened for drug use within the past 90 days. During the test, the proctor will gather a hair sample of approximately 70-120 hairs, which will generally be gathered from close to the crown. The procedure is painless, and you do not have to worry about it invading your privacy.

One of the most common questions about how to pass a hair drug test is whether or not you can simply shave your head to avoid taking the test altogether. This is not advisable. If you do not have any hair on your head, then a sample of body hair will be taken. Body hair grows much more slowly than the hair on your scalp, and drug metabolites can stay present in your body hair much longer than in the hair on your scalp.
