how long will persciption drugs stay in your system fro a hair folical test
Dear customer,

The hair follicle drug test consist of two parts, the presumptive and confirmatory test.Any positive presumptive test is confirmed by confirmatory test that uses mass spectrometry and can detect the drug in a hair follcle as long as 90 days after the last dose.It also depends on the frequency and chronicity of its use.

Let me know if you have any doubt.

Thank you
