    You can do this by using content regions in the head, in exactly the same way as you would in the body of the page. eg, In your masterpage:

    <head>
    <link type="text/css" rel="stylesheet" href="/styles/common1.css" />
    <script type="text/javascript" src="/scripts/common1.js"></script>
    <asp:contentplaceholder id="ExtraStylesAndScripts" runat="server" />
</head>

    And then in the page itself just something like:

    <asp:content contentplaceholderid="ExtraStylesAndScripts" runat="server">    
    <link type="text/css" rel="stylesheet" href="/styles/extra1.css" />
    <link type="text/css" rel="stylesheet" href="/styles/extra2.css" />
    <script type="text/javascript" src="/scripts/extra1.js"></script>
    <script type="text/javascript" src="/scripts/extra2.js"></script>
</asp:content>

    For stylesheet you can use this : 

    HtmlLink cssRef = new HtmlLink();
cssRef.Href = "addins/main.css";
cssRef.Attributes["rel"] = "stylesheet";
cssRef.Attributes["type"] = "text/css";
Page.Header.Controls.Add(cssRef);

    For Meta Tags : 

    HtmlMeta metaTag = new HtmlMeta();
metaTag.Name = "author";
metaTag.Content = "ScarletGarden";
Page.Header.Controls.Add(metaTag);

    But there is no way to add external script files to header element.

    You can add inside body element by : 

    if (!ClientScript.IsClientScriptIncludeRegistered("myExternalScript"))
{
   ClientScript.RegisterClientScriptInclude("myExternalScript", "js/myJSFile.js");
}

    Hope this helps !

    You can declare the page title in the content page declaration.

    <%@ Title="Page Title" Page Language="C#" AutoEventWireup="true" CodeFile="Subpage.aspx.cs" Inherits="Subpage" MasterPageFile="~/MasterPage.master" %>

    I haven't tried this.
    But you can put HEAD element inside html with the enclosed string in asp style markup.

    e.g. <%=myTitle%>
