html_header.php is where that info is output, though not initially generated... couldn't hurt to look at that and see if you have a modified template copy.
The page title can be generated in meta_tags.php. Do you have any specific ones around here?
PHP Code:
// Per-Page meta-tags. Follow this pattern for individual pages you wish to override. This is useful mainly for additional pages.
// replace "page_name" with the UPPERCASE name of your main_page= value, such as ABOUT_US or SHIPPINGINFO etc.
// repeat pattern as necessary
define('META_TAG_DESCRIPTION_page_name','');
define('META_TAG_KEYWORDS_page_name','');
define('META_TAG_TITLE_page_name', '');
On another topic, I notice you have the header background switching colors for different pages - appropriate for a site on hair dyeing:)
But it flickers distractingly when switching. You actually use a new image loaded on the page for each one; it would work smoother and faster if you put all those backgrounds into one image file and used the "sprites" technique to show it as a background-image in your stylesheet, moving it to reveal the correct part for each page. Smart Backgrounds in Free Addons can help make this easy. (The current released version doesn't talk about sprites and requires the existence of separate files, but you don't have to use or load the rest; the style rules can all move a single bg image around.)
