How does hreflang work?

hreflang tells Google about localized versions of a page.

Example:

<link rel="alternate"
      hreflang="en-us"
      href="https://example.com/us/page">

<link rel="alternate"
      hreflang="en-gb"
      href="https://example.com/uk/page">

Implementations should be consistent and reciprocal.

A page should generally identify its alternate versions, and those versions should reference the relationship correctly.

hreflang is about localization, not a generic duplicate-content fix.
