Get parent category name when only child category is applied to a product

Question

I'm trying to get the parent category of a product when actually it's assigned to a child category of the parent, but not the parent itself. The function below works when I assign both the child and parent category for the product. But I want only to assign the product to the child category and in the same time to display the parent category too. Like that in this order: ChildCatName - ParentCatName Could you please point me in the right direction? Thank you!

    //Woo Cat product
    $woo_single_cats = get_the_terms( $post->ID, 'product_cat' );
    
    if ( $woo_single_cats && ! is_wp_error( $woo_single_cats ) ) {
        
        $woo_single_cat = array();
        
        foreach ( $woo_single_cats as $term ) {
            $woo_single_cat[$term->term_id] = $term->name;
        }

        $woo_single_cat = apply_filters('seopress_titles_product_cat', $woo_single_cat);

        $woo_single_cat_html = stripslashes_deep(wp_filter_nohtml_kses(join( " - ", $woo_single_cat )));
    }

Check if it works for you... i have modified the loop
/Woo Cat product $woo_single_cats = get_the_terms( $post->ID, 'product_cat' );

    if ( $woo_single_cats && ! is_wp_error( $woo_single_cats ) ) {
        
        $woo_single_cat = array();
        
        foreach ( $woo_single_cats as $term ) {
            $woo_single_cat[$term->term_id] = $term->name;
            $term_parent_id = $term->parent;
            $parent_term  = get_term($term_parent_id, 'product_cat');
              
        }

        $woo_single_cat = apply_filters('seopress_titles_product_cat', $woo_single_cat);

        $woo_single_cat_html = stripslashes_deep(wp_filter_nohtml_kses(join( " - ", $woo_single_cat )));
    }
