Cannot add style in wp_head if inside another function

// Function to add styles in the admin header only for plugin page
add_action('admin_head', 'abc');
function abc()
{
    global $pagenow;
    // Check if the current page is your plugin's settings page
    if ($pagenow === 'admin.php' && isset($_GET['page']) && $_GET['page'] === 'my-slug') {
        echo "work so good";
    }
}

// Render plugin settings page
function my-plugin-page-settings()
{
    // Adding scripts/styles in the admin head for this page
    add_action('admin_head', function()
    {
        echo 'not work at all';
    });
    
    // Adding scripts/styles in the admin footer for this page
    add_action('admin_footer', function()
    {
        echo 'work so good';
    });
}

So, i need to filter via global pagenow, cause not work if inside my plugin page function (but here, indeed, work so good admin_footer).

someone can help me to best understood?
