You can have a global middleware for that. something like:

header('Cache-Control', 'no-cache, must-revalidate');
        // Or whatever you want it to be:
        // $response->header('Cache-Control', 'max-age=100');

        return $response;
    }
}

then just register this as a global middleware in the Kernel file:

protected $middleware = [
    ....
    \App\Http\Middleware\CacheControl::class
];
