Follow this pattern Maybe it will help you

IN controller

<?php
function show_home() {
    $data['page'] = 'home';
    $this->load->view('header',$data);
    $this->load->view('home');
    $this->load->view('footer');
}
function show_contact_us() {
    $data['page'] = 'contact_us';
    $this->load->view('header',$data);
    $this->load->view('contact_us');
    $this->load->view('footer');
}
 ?>

Create helper meta.php

<?php
    function meta($page) {
        $meta = '<meta charset="utf-8">';
        switch ($page) {
            case 'home':
                $meta .= '<meta name="description" content="Home page description">';
                $meta .= '<meta name="keywords" content="Home page keywords">';
                break;
            case 'contact_us':
                $meta .= '<meta name="description" content="Contact us page description">';
                $meta .= '<meta name="keywords" content="Contact us page keywords">';
                break;
            default:
                $meta .= '<meta name="description" content="default page description">';
                $meta .= '<meta name="keywords" content="default page keywords">';
                break;
        }
        return $meta;
    }
?>

load meta helper in autoload.php

$autoload['helper'] = array("meta");

call meta function in your header for individual view

echo meta($page);
