The HEAD section is the worst place to load scripts. It’s painfully slow. The more and the bigger the worse it gets. Move the scrips to the bottom of the page and you cannot use HTML5 and CSS3 safely.
The single best solution to this universal problem is to include Head JS on top of the page and load rest of the scripts with it. Head JS speeds up, simplifies and modernizes your site. Head JS loads scripts in parallel without blocking the page. The performance will be improved even with a single minified script.
