Not sure what the huge revelation is.
Everything that you put on your head (and most other parts of your body) will go systemic to some degree. RU has a 2 hour half-life, but this is enough to traverse your entire body dozens of times over and bind wherever it is going to bind.
There is no free lunch with topicals, especially not with the standard Ethanol-PG vehicle which is asking for systemic side effects.
This is why - back in the time when anyone still gave a sh*t about RU - they developed RU-myristate, a prodrug, that could then be loaded into solid lipid nanoparticles and vastly improve the delivery to the hair follicle while minimizing systemic impact.

Not something the average person can cook up at home, so I wouldn't even bother with RU.
