# @next/next/no-head-import-in-document

> Disallow importing `next/head` in `pages/_document.js`

There are two `Head` components. The one from `next/head` is for pages. It updates the `<head>` as the user moves from page to page. `pages/_document.js` is only rendered on the server and needs the `Head` from `next/document`.

The rule reports every `import` of `next/head` in a file named `_document.*`, or named `index.*` in a `_document` directory.
