Depends: on if looking for alcohol. Most hair follicle tests will pick up@6 months back.

Not likely: Hair testing, which can test for by-products of alcohol metabolism, are useful for frequent, excessive testing. It's not sensitive or specific for infrequent, low level drinking, as the byproducts do not "build up" to any appreciable levels in the hair.
