@Supernova122:
So where's your issue with the internal logic here?
That this dimension is only accessible to people with the same sharingan as Obito, which was clearly stated before and is reason why Kakashi is able to fight him in the first place. Hinata does not have such a sharingan. And before you start arguing with some hidden abilities or byakugan stuff, Hinata actually used the byakugan before trying to detect Obito's chakra and also was puzzled by what's going on and not detecting it while he was in the other dimension.
It contradicts previously etablished statements and internal logic of abilities. If it is stated that, for example, Naruto's new rasengan destroys opponents on a cellular level, then it cannot suddenly have the opposite effect without any adequate explanation (and even if this happens and is explained, if it was not foreshadowed in any way it is still bad writing and probably borders towards things like Deus Ex Machina or simply Asspull, depending on the context). If the ability actually suits the general premise of the character/his abilities, as say Luffy in One Piece and Gear2/3 (both based on him being rubber and pumping air into body parts and do not contradict previous statements about his power) or Sasuke to an extent and his ability to summon the huge snake (even though it was a low point of bad writing, the Deidara fight showed Sasuke is easily able to use Sharingan to control huge snakes, making it rather plausible he is able to control this one as well and it fits his theme of being Orochimaru's former disciple and he was shown before to be able to summon large creatures), then it is not much of an issue. It still can be badly executed and does not imply good writing in itself, though.
So, to get to the hair issue: the issue is not really internal logic, but would not make much sense at this point considering etablished abilities. The Hyuga clan has abilities based on chakra point pressure attacks and byakugan, which helps their fighting style. Energy attacks, let alone body control on a level as advanced as hair control, was never mentioned before as a speciality of the Hyuga clan and thus would be quite similar as my rasengan example above: random asspull out of convenience and, especially at such a late point in the story, a prime example of an asspull and making up things as the story goes on.

Also, people saying it's ridiculous she could have made them - the number is not so large. Supposedly, based on certain assumptions on paper size and density, the world produces 95 trillion sheets of paper per annum. So the number Konan used is about 1 in 160 of modern global annual production. Considering that explosive tags are quite small, the mass would be an even smaller proportion. And considering ninja powers, it does not seem so odd that she could set it up with the significant effort that it is implied she put into setting that up.
It atually still is very, very far-fetched. As Nobodyman said, you do not seem to be aware just how large 600 billion is.
Let's first consider that she, most likely, did not have all of those tags prepared in her closet or whatever. Why? Because, as you can see from the Pain fight and its surroundings, there was no long-going plan to defeat or kill Obito. So most likely, she prepared all of those tags in the time between Pains death and the Obito fight, a period of (too lazy to look this up so I am just estimating) maybe a month. We cannot say for sure if this is true or not though, but I would like you to keep this in mind.
Now, let's first assume she takes one second to create one tag. That means she would still need around 20,000 years to create 600 billion tags. Put differently, to finish all tags within one year of nonstop working, she has to produce 20,000 tags per second. I really do not think that, even in the ninja world of Naruto and with paper-transformation abilities, this is feasible.
The matter with this number is not the typical shounen thing with "OMG he can lift 100000000 tons!". That's merely powerlevel stuff. It's more like saying "OMG he run all around the world which amounts to several million kilometers!", which makes simply no sense geographically. You cannot compare this number of 600 billion to anything and it just seems to be totally random, basically having the same effect as, say, 600 million, which also would have been feasible to create some kind of ocean and at the same time actually make some more sense because it is not ridiculously large. Basically, 600 billion looks like the wealth of Dagobert Duck in old comic book magazines, where it is intended to be ridiculously over-the-top and a joke.
