I just recently smoked weed. I've smoked about 4-5 times in the last 2 months. Each time was one session per every Saturday at the beginning of the 2 months, last time was 3 weeks ago. Each session was 3-4 hits.. I have never smoked before this, and decided to quit for fear of random drug tests (urine). Now I am applying for a new job, and they test hair follicle.. Is it likely I'll pass? Will "shampoos" increase my odds of passing?

Infrequent use of cannabis is unlikely to be detected in a hair drug test (HDT). ".. hair testing is unlikely to be positive for marijuana until the tested student has used marijuana at a rate of about twice a week in the prior 90 days..." (DuPont 2008)

This is a consistent finding in the research. “Basic drugs such as cocaine and methamphetamine concentrate in hair due to ionic bonding to melanin, the pigment in hair that determines hair color. The more neutral and lipophilic THC is not strongly bound to melanin, resulting in much lower concentrations of THC in hair as compared to other drugs of abuse. (Huestis)

Have never looked into the various shampoos.
