First, you seem to have a doctor that has some grasp of hair testing based on his assessment of your chances for passing. That is in accord with my opinion and more importantly existing research.

I will recommend to you some practices and products (generic) with the understanding that there is no specific published research to support their use. Along the same line each recommendation is based on specific scientific findings in relation to specific chemical interactions and well elucidated physiologic processes. With others, we have tested the methods in only a very limited number of individuals. 33 in total. Our system is developed in relation to cannabis metabolites only and there is no reason to believe it would work for others.

That information is provided so that you understand that past results of the 33 tested individuals* is far too small to generalize to population and therefore you must acknowledge that there are no guarantees.

With those restrictions acknowledged, the process does not seem to damage or alter the hair and may in fact be beneficial to appearance. It involves no caustic substances. To date we have used a total of three (3) treatments on each of the 33 individuals. Each treatment ranged from 1 - 2 hours. The chemicals used are available OTC and total cost is less than $20 (mix your own). Furthermore the chemicals are not, and can never be, classed as adulterants.

It involves heat/steam and you must have or purchase a hair steamer or a good hair dryer (about $20) with attachable bonnet (about $10) and a method for inserting the liquid (small plastic tube) into the tubule of the heater. As a last alternative a couple of shower caps and absorbent cloth can be used**.

If all of that is agreeable to you we'll work through it step by step.

*in our group only 16 of the 33 individuals had been pre-tested for THCA content. As your doctor and research indicates some or all of these people may have had no THC to begin with.

**this method can be problematic for those with longer hair. Effectiveness could be greatly diminished.
