undefined variable when i called it on a header view in laravel

My route is:

Route::get('header','HomeController@header')->name('header');

My functionality is:

public function header()
{
    $header=ParentCategory::latest()->get();
    return view('includes.header',compact('header'));
}

My view foreach loop is here:

@foreach($header as $pc)
    <li class=" aligned-left parent dropdown " >
    <a href="index7fa3.html?route=product/category&amp;path=18"
        class="dropdown-toggle" data-toggle="dropdown">
        <span class="menu-title"></span><b class="caret"></b></a>      
@endforeach

I don't want to write their route which name is header, mention in browser I want to work my foreach loop without route name, header.
