How to extent Auth object in Laravel?

I have a default table users and related table user_details.

When user does auth it retrieves data from users table and is available to global object:

Auth::user()

How to extend Auth::user() with data from related table user_details?

Reason is to show a full information about authenticated user in each pages(at header)
