Blog- Adding Category as title to category results feed

I was wondering, is there a way that when a user clicks on a blog category and then gets a results page of only posts put in those categories, to have the category show at the top of the page so they know where they are? (like on the shop, when you click a category, you can show the category title or breadcrumbs). 

I assume it would be probably a script or code injection. Any help is greatly appreciated.
