If I Stay Clean For 4 Months, Will I Pass A Hair Follicle Drug Test?

It depends on how far back they go on the hair follicle test, most places only go back about 90 days, but I have known of some going back almost a year. There are shampoos you can buy to wash your hair with and pass a test and also a product called blue will clean your hair, blood,saliva, and urine

Maybe. The hair follicle test will go back about 90 days. So four months in you may be okay. I would do some research. Just go to ask.com and type in "how long does a hair follicle test go back" that's what I just did. Lots of stuff came up. :)

The answer is NO even if you shave your head the oils in the scalp secrete the thc for months
