Another item you will need is some test strips for checking pH of water. They are cheap and you can get at any pharmacy. Since you will be making this want it to be within a pH range. While there check for the availability of trisodium phosphate, a cleansing agent. Won't need much, down the line will need about 1.25 teaspoons per gallon of water.

While I don't recommend any specific lab for testing, Psychemedics uses the lowest cutoff and has a home test available. HairConfirm is another that seems more widely available (pharmacies, stores, etc). I have no specific direct experience with the latter. They are about same price.
DrBill100 Reviewed by DrBill100 on . Just found out I have to have a hair follicle test Well, I've been reading on this forum for hours and hours and feel doomed. I've been working for the same company on and off for 17 years -- this time 5 years as a contractor. Just found out they wanted to hire me two weeks ago, so quit smoking 12 days ago. (I smoke once per night in the evening everyday on and off for mostly 7 years now). Anyway, I was good with the usual urine test next week but have now found out it's a hair follicle test. I purchased today from TestClear Zydot Ultra Rating: 5
