Drug testing through hair is relatively insensitive to single uses of marijuana. While the detection period for hair tests is typically around 3 months, most cases of a single use of marijuana would NOT cause a positive hair drug test.

No matter what the quantity was?

Obviously, the heavier the use, the more likely it would be to have a positive test. Generally however, hair testing is relatively insensitive to rare/single uses, and much better at identifying more regular use.
