Okay, considering a job that does a hair follicle test. Best method results for passing one was using Nexxus Aloe Rid and Zydot Ultra Clean shampoo, if you do not know that Aloe Rid shampoo is discontinued but still sought out therefore making it extremely expensive, usually around 150-240. Upon further research I found that the reason for this is because it contains propylene glycol which helps the Zydot shampoo penetrate the center of the hair follicle, beyond the 12 layers of cuticle, and get rid of the thc. My quest is, couldn't I just buy propylene oxide as it is very cheap, use it alone or mixed in with a shampoo and then use the Zydot? Any insight from anyone?
