Also the system when using this type of testing is more difficult to mask drugs.
Hair follicle drug test employees are required to take samples of hair, usually just a small piece of hair is taken and is considered less embarrassing than urine collection. A human resources or other government employees within the company often can store on site hair. The sample is sent to the lab for washing and testing.

While some products claim to mask the presence of drugs in hair samples, most are based on false or inaccurate claims. Hair follicle drug testing more effective and less invasive than other options have been proven to be.
