hide certain subcategory

Hi!

I have tried to hide a certain subcategory from my shop(shop page and other pages, there is a category widget).
I found that the code below works for all pages except the shop page. If i change is_product_category() for the is_shop(), so it works for the shop page, but not for the other pages.

How can i do that it works for ALL pages (shop and all others)?

add_filter( 'get_terms', 'get_subcategory_terms', 10, 3 );

function get_subcategory_terms( $terms, $taxonomies, $args ) {

  $new_terms = array();

  // if a product category and on the shop page
  if ( in_array( 'product_cat', $taxonomies ) && ! is_admin() && is_product_category() ) {

    foreach ( $terms as $key => $term ) {

      if ( ! in_array( $term->slug, array( 'seinakellad','nastennye-chasy','wall-clock' ) ) ) {
        $new_terms[] = $term;
      }

    }

    $terms = $new_terms;
  }

  return $terms;
}
