<p>The quotes don't explicitly say that Shinobu was wearing the hat to stop Koyomi from rubbing her head, but it seems pretty plain from the context. It was her way of telling Koyomi, without deigning to speak to him, that she hadn't forgiven him. </p>

This reminds me… the first thing Shinobu, in her full-powered form then, did after Araragi returned from hell in owarimonogatari is rubbing Araragi’s head. The fact that she regained her full power and yet pledge loyalty to Araragi said a lot.

<p>Shinobu originally didn't have a hat, but in Nekomonogatari Black, Shinobu ask Oshino to buy her that hat, he gave it to her as a reward since she was the one who resolved the problem with Black Hanekawa. But since she live in Araragi's shadow, she started to talk more and didn't wear that hat anymore, any specific reason why is that?</p>

For one thing you look cuter without that motorcyclist/pilot hat :) I suppose it's the main reason why the animators decided to remove it from Shinobu's everyday outlook.

@user1306322 but I think there's more to explain, since Oshino mention it that Shinobu herself ask him to buy her a hat and the fact that she become really different person (more talkative and cheerful) after she live in Araragi's shadow. There's a reason why she become more talkative but I don't remember seeing any explanation about her hat.

This is off the top of my head, so I could be barking mad, but this is how I remember it. Spoilers for Kizumonogatari, Nekomonogatari Black, and Nisemonogatari ahead.

Shinobu, in Kizu, tells Koyomi that head-patting is some kind of intimate act of subservience between a vampire servant and master. Koyomi thinks this is a little weird, but goes along with it.

At the end of Kizu, Tsubasa deduces that Shinobu wanted to die the whole time. Koyomi refuses to grant her this, and instead brings about the situation where he's an asymptotically human pseudo vampire and Shinobu is a mostly powerless asymptotically vampiric pseudo human who has to suck Koyomi's blood to survive. Shinobu is furious, and doesn't talk to Koyomi until Karen Bee.

In Neko Black, Shinobu helps defeat Black Hanekawa. Afterwards, Koyomi goes to pat her on the head as a reward, but finds that she's wearing that strange pilot hat. She got the hat to show Koyomi that she was still pissed at him and wasn't going to let him pat her on the head.

Later, in Tsubasa Cat, Shinobu stops being angry at Koyomi and starts living in his shadow. In Karen Bee, she even comes out to talk to him when he's in the bath. Since she's not mad at him anymore, she stops wearing the hat, since she doesn't need to stop him from patting her head.

Edit: Now with actual evidence.

Kizumonogatari, Chapter 4 establishes that head-rubbing is regarded by Shinobu as a sign of obedience. Koyomi has just allowed Shinobu to turn him into a vampire, and Shinobu has asked him if he understands that he must be subservient to her. The first to speak is Koyomi.
