Good news for those of you facing a hair test... A close friend, a moderate user (3-4 times a month, basically a big fatty every weekend) just passed his test, which was performed by APL out in Las Vegas. He stopped smoking completely about three weeks before he took the test. Then, for five days he washed his hair twice a day with Nexus' Aloe Rid Shampoo (about $5 for a 5-oz bottle) and followed it with the Aloe Rid Treatment (about another $5); then he got a perm--about $45. He didn't cut any hair OFF, just had it permed. His hair's about eight inches long and dark brown. Two days later, on the morning of the test, he did the Afterburner/Nitro treatment (about $160 with shipping from hairtest.com), following the instructions that they sent, which says to soak the hair in vinegar prior to the treatment to soften the shaft. Neither of us are associated with Nexus or Afterburner, so this isn't a sales pitch, those were just the only two products that we read on the web that people said had worked. The active ingredient in both those shampoos is Edta, which is what gets the trace minerals and medicine residue out of your hair; I think any shampoo with that ingredient would help clean your hair out, not just these particular brands. The perm also really helped--his stylist (who is also a member of the 420 club) says that a perm actually affects the inner layer of the hair, which is what the test is trying to read. Make sure, though, not to smoke anymore after you get the perm--after a perm, your hair is actually MORE likely to store toxins, possibly because the hair is more porous. Also, I think he threw in a couple of prayers just to be safe. Anyway, he just heard today that he passed. And his hair doesn't look too bad--personally I would rather have some curls that a shaved head. This test is getting more and more popular; we all have to work on sharing information about how to pass it... what we choose to do in our free time should NOT be open to our employer's scrutiny!
