If you're referring to feeding a GFCI circuit with another GFCI circuit, then I completely disagree. GFI circuits feed GFI circuits all time when adapters are used from a 20 amp outdoor GFCI protected circuit to feed an RV which has GFCI protection after the RV main panel.
GFCI circuits being unable to feed another GFCI protected circuit is an old wives tale.
What I am saying is to feed separate or individual GFCI receptacles from one breaker by not using the existing OEM GFCI feed through receptacle in its original configuration. That is also not a problem.
P.S. - Most newer hair dryer blowers come with a GFCI unit built into the cord/plug unit. They are most always plugged into bathroom receptacles which are required to be GFCI protected. In other words they are designed knowing that a GFCI protected circuit will feed a GFCI protected hair dryer.
