maxcady on "Do I need the head tag in the header php file?"

I was wondering if I need the </head> tag in any template on wordpress.

I notice that when I take it out, my site still looks the same AND I don't get the malware injected in the header if I remove the tag.

I've removed it on a few sites and everything looks and works great still.

Am I messing something up if I remove the </head> tag in the header.php file?

Thanks
