Yes and no on that. There are limits so more to follow on this.

That's not really accurate. One, THC is not stored in the hair follicle. THC is deposited in the hair from the blood and not stored in the follicle. I know sometimes you will hear the term "hair follicle test" but that is really not what they are testing. They are testing the hair shaft. Second, THC will be deposited for a few days even after smoking because of high levels of THC still circulating in the blood. Your urine may test postive still for THC but depending on your smoking history, the blood levels will fall and the hair will stop receiving high enough levels of THC to test positive. Third, in addition to these extra days you have to account for the time needed for this dirty hair to grow out from the follicle to the point where it is far enough out of the scalp to get cut. This is usually 7-10 days. Fourth, if his hair is too short one of three things will happen:

1) They will use body hair
2) They will use nail shavings.
3) Failure due to refusal to submit sample.

Good job Greendove. Maybe you read my posts about how they can only go back 90 days! Maybe not. Also, you are right the only 100% way to pass the hair test is not to use for a little over 90 days. I think though since this person is willing to quit way before the test and keeps his short to begin with I think he can have a few more weeks to enjoy.

Let us see how long this person has. First I would like Pixel to read my post in this thread to learn a little more about the hair test.

Head hair grows at about the rate of .53 inches per month. 1 and 1/2 inches of hair is 90 days of history. So if Pixel keeps his hair at this length or longer it would be safe to smoke till late January, say Jan. 25th or so. That would give him time for his body to stop depositing THC in his hair and for the dirty hair to grow out (3 days +10 days). So from about February 10th (4 more days thrown in as a precaution) onward his hair will be clean, easily giving him time to have 1 and 1/2 inches of clean hair.

Pixel, if your hair is shorter than this we can figure out what your end date should be, which will be a little later than Jan. 25th but I wouldn't want you to push it too much. You also don't want your hair shorter than about 3/4 of an inch or some collectors may want to go for body hair which has slightly different grow rates.
