#1
RewriteRule /index.php=HairThing$ http://www.mydomain.com [R=301]

#2
RewriteCond %{HTTP_HOST} ^mydomain.com 
RewriteRule .*   http://www.mydomain.com [R=301] 

However, example case 1, as said by Greg, will always put the / on if it is without a uri.

mydomain.com  # impossible 
mydomain.com/ # possible
mydomain.com/foo  #possible
mydomain.com/foo/ #possible
