Hmm... didn't even know you could test for drugs that way (shows what I know!). However, reading up on this test reveals the following:

"Blah. blah. blah (about the test). Therefore a 90 day history of drug use would require a minimum of one and one-half inches of hair length measured from the root line. Regardless of length of the hair sample submitted, test results are limited to 90 days of historical drug use as detectable levels of chemical structures in the core of the hair shaft deteriorate rapidly after this time period."

As such, 2 months is pretty good to get rid of it it seems. Plus 30 days history is half inch. Hence:

** Can you have your hair cut now removing pretty much all of it and then stay clean for the remaining two months **

This should then mean you are pretty untraceable I would suggest. I.e. you have decent hair growth after two months so as not to make it obvious, but the new growth should be pretty clear. To make it even better, cut another half-inch off your hair (i.e. growth from today) just before the test - no need to remove all of it though.

What's the test for by the way?

Oh and I doubt shampoos would work?? It looks like the drug actually is inside the hair root. You could combine shampoos with the above method though for double-safety?!
