The Hard Hat
One good way to protect your hat
(and, in turn, your head) is filling it with something dense. Or perhaps you've got a steel plate in your skull from a long-ago injury, that happens to be just what's needed
to deflect a bullet
or psychic attack

Anime and Manga
- Shishio Makoto from Rurouni Kenshin wears a headband lined with steel - the only piece of armor he wears. The reasoning lies in the events of his original 'fall', when he caught a bullet to the forehead, paralyzing him for a while, and giving his enemies time to burn him. He wears the headband to ensure that it never happens again, and it does indeed prove remarkably effective...
- Gauron of Full Metal Panic! is revealed to have installed a titanium plate in his forehead due to an earlier injury, and hence is the reason he survived Sousuke's bullet to the head and lives to terrorize poor Sousuke some more.
- Bean Bandit from Gunsmith Cats tops his bulletproof ensemble with an impact resistant headband. That apparently weighs at least twenty pounds. He wears this on his forehead.
- Jotaro Kujo from JoJo's Bizarre Adventure gets stuck by a bunch of knives from multiple directions while he's fighting DIO. It's revealed that at some point he shoved a bunch of magazines under his clothes and hat, which kept the knives from doing deep damage.

- In He-Man and the Masters of the Universe (2002) it is shown that under his helmet Ram Man appears to have a metal plate grafted to the OUTSIDE of his head.

It isn't stated if this is because of an old injury but seems plausible considering his teammates Mekaneck and Fisto got their respective metal parts following battle injuries.
- Truth in Television; Bowler hats were conceived as alternatives to top hats that were better able to protect the wearer's head. A properly made one is quite rigid.
- The same goes for modern police hats (they look like soft caps, but they're quite hard). Also, the Victorian predecessors to British Coppers' distinctive dome-shaped helmets were simply reinforced top hats.
- Hard hats, of course. Which were reportedly inventednote by Franz Kafka, of all people, while he was working as an insurance agent in Prague.
- Before these there was the kettle hat, a late-medieval to early-modern combat helmet that was basically an ordinary hat of the day, but made of iron (the German and French names for the helmet, Eisenhut and chapel-de-fer, both mean "iron hat"). It was most common for commoner foot soldiers, as it could be made cheaply in large numbers (only professional armourers could make a proper helm, but any village blacksmith could make a hat out of iron) and its wide brim afforded extra protection without special fittings (and kept the soldiers from being dazzled in the bargain). They were particularly favoured by the New Model Army, which included a derivative form called the morion as part of the standardised uniform.
- Armor in general—including helmets—disappeared after the Thirty Years' War, but helmets of this type saw a resurgence in World War I, when the French Adrian and British (and later American) Brodie Helmets were explicitly modeled after the kettle hat.
- Interestingly, around the same time European lords were decking their footsoldiers in kettle hats, the Japanese daimyo gave their ashigaru (i.e. peasant footsoldiers) conical hats made of iron.
- Some companies issue baseball caps with a hard (plastic) insert to their employees as a protective device, e.g. for people loading trailers.
