Keep Header Throughout Site

When I click into my individual posts, I lose my front page header that otherwise is visible throughout every other page on my site. The other problem is that the page begins above the site title banner, so that the name of the post is cut off.

Is there a way to carry out my primary header to these posts as well so that I can display the whole post as attractively as every other page on my site?
