Google Font in admin area

Hello guys!

I wanna include google webfont in admin section i did it but IE font is looking so weird and bigger. I have googled and have got some good result but they said add some meta tag in header section of the theme.

Question: How to add custom meta tag in wordpress admin section is there any hook or function do guys know?


Thank you.

This is a function to add to the header in the WP admin, add this to the functions.php

function custom_admin() {
 echo '<meta name="" content="" />';
}
add_action('admin_head', 'custom_admin');
