Its shining gold hair provides it with protection. It’s reputed that keeping any of its fallen hairs will bring bad luck.

Alolan Dugtrio is graced with luscious golden hair. Its hair is a reference to Pele’s hair, a form of thin volcanic glass formed near Hawaii’s volcanos, which is I guess what gives it the Steel typing. Its typing of Ground/Steel, while not unique, is pretty uncommon. It’s only shared by Excadrill and Steelix (though Steelix is technically Steel/Ground).
In the anime, there was an Alolan Dugtrio owned by a DJ. It’s quite famous, and each of the heads has a separate personality and name (and are sometimes at odds with each other).
One of its abilities is Tangling Hair, which is a signature ability to Alolan Diglett and Alolan Dugtrio. It lowers the foe’s speed by 1 stage if hit by a contact move.
Stat-wise, it has high Attack and Speed (despite its UltraSun Pokedex entry saying that “Its metallic whiskers are heavy, so it’s not very fast”), but low defenses and HP. Compared to Kanto Dugtrio, it has 10 less Speed and 10 more Defense.
