Yes, but people who don't care about safety and/or are cheap aren't
likely to use them either. And you have to only use that one. If
some repair guy, (like the AC repair guy that the code is worried about)
shows up and just plugs a regular cord in, they are not protected.
Or if you have one GFCI cord and need more at Xmas, same thing, etc.
And none of that protects against dropping a hair dryer into the tub.
the GFCI cords are certainly better than nothing. And any repair
guys should have them, since they don't know what they are dealing
with at each house.




I have seen some hair dryers with a GFCI , or something like it) on the
dryer cord.


That is an immersion detector, similar to a GFCI except the reference
point is to a wire ring inside the throat of the hair dryer, not in
imbalance of the in and out current.
Actually BOTH exist. The Wellong P8S is a commonly used GFCI plug
assembly allong with the outdoor rated 3 wire GF9
