Will GFCI work with items without equipment ground
I know it's probably a dumb question but my wife's hair dryer is old and has no equipment ground. Wanted to be sure she is still protected if it should be dropped into water or otherwise shorted.

Not sure if it still is, but adding a gfci outlet to a two wire system was a code approved way to add an outlet with a ground pin, even though it was not grounded.
yep, still permitted just need to add "no equipment ground" label to outlet.

Thanks to NECreader who commented on 2016/06/13:
This article should state that NEC 406.3 permits GFCI receptacles to replace two prong ungrounded outlets:
(3) Non–Grounding-Type Receptacles. Where attachment to an equipment grounding conductor does not exist in the receptacle enclosure, the installation shall comply with (D)(3)(a), (D)(3)(b), or (D)(3)(c).
(a) A non–grounding-type receptacle(s) shall be permitted to be replaced with another non–grounding-type receptacle(s).
(b) A non–grounding-type receptacle(s) shall be permitted to be replaced with a ground-fault circuit interrupter type of receptacle(s).
These receptacles shall be marked "No Equipment Ground." An equipment grounding conductor shall not be
connected from the ground-fault circuit interrupter-type receptacle to any outlet supplied from the ground-fault circuit-interrupter receptacle.
(c) A non–grounding-type receptacle(s) shall be permitted to be replaced with a grounding-type receptacle(s) where supplied through a ground-fault circuit interrupter.
Grounding-type receptacles supplied through the ground fault circuit interrupter shall be marked "GFCI Protected" and "No Equipment Ground." An equipment grounding conductor shall not be connected between the grounding type receptacles.
