SWIM has a plan for acing a hair test.. Will it work?

[mauijim66]

Ok, swim thinks he has a great job opportunity down the road. The catch is, he'll have to pass a hair test.
Now, swim caught a buzz daily for a few months, then stopped four weeks ago. Swim has been shaving his head for years, but his hair grows back quickly.
What he's wondering is this:
If he last shaved his head a couple of days ago, and now lets it grow on out, will it be clean? He plans to eliminate ALL body hair (in sections) over the next month or two-- the time leading up to the test.
Will this work?

geeeez.. NOBODY here can give me a little insight on this matter?

Let me provide a little insight on the current status of your scalp hair. Use of an emulsifying, cleansing, penetrating agent would be very beneficial. THC and THCA are deposited in your scalp via the sebaceous glands sitting right below the epidermis and you have cut end of the hair exposed by way of the follicle and the cuticle of the growing hair is softer than after it emerges . So don't miss the opportunity to treat the hair as it grows.

Hey drbill! Thanks for the info.. I guess what i'm really curious about is this:
We all know that (roughly) your body is clear of thc metabolites in about a month after the last use. (or maybe by then there are too few to reach the threshold of detectibility for a urinalysis test.
Either way, isn't the hair folicle 'tagged' by the metabolites while they are in the system? In other word, wouldn't new hair growth be 'clean' if it sprouts up, say, a month after the smoker's last toke? And if not then, when? A shorter period of time? Longer? Much longer?
Whats an example of a penetrating emulsifying agent, btw?

You can have THC and THCA in your system and not in circulation. The best information to date (Smeal) indicates that THC (meaning both metabolites) enter the hair by indirect deposition into hair from surrounding scalp tissue. THC is found in the sebaceous glands imbedded in your scalp and is also stored in the basilar levels of the epidermis. THC is deposited in urine via circulation and may never reach the level of detection due to the erratic nature of release from fatty tissue (a little here, a little there). In urine you are looking at a cutoff of 50 ng (billionth). In hair testing the cutoff can be as low as 0.05 pg (trillionth) and it doesn't take much to reach that threshhold. So if the THC is releases from the epidermis it could very well enter the hair while never returning to circulation.
