Remove stylesheet from pages & home page

I want to remove the plugin’s stylesheet from loading on anything except a single post.

On a simple blog site the following code works removing from the home (posts) page.

function dequeue_scriptless_sharing_css() {

    if (is_home()) {
        wp_dequeue_style(‘scriptlesssocialsharing’);
    }
}
add_action(‘wp_enqueue_scripts’, ‘dequeue_scriptless_sharing_css’, 20);

On another site (linked one) it has a static page as the home page and therefore this code should work.

function dequeue_scriptless_sharing_css() {

    if (is_front_page()) {
        wp_dequeue_style(‘scriptlesssocialsharing’);
    }
}
add_action(‘wp_enqueue_scripts’, ‘dequeue_scriptless_sharing_css’, 20);

But it doesn’t. And neither does targeting individual pages either by page name or number.

How would I go about removing the stylesheet loading on pages?
