To start with, do something like this:

 

<data:DataGrid>
    <data:DataGrid.Columns>
        <data:DataGridTextColumn Header="My Header">
            <data:DataGridTextColumn.HeaderStyle>
                <Style TargetType="dataprimitives:DataGridColumnHeader">
                    <Setter Property="ContentTemplate">
                        <Setter.Value>
                            <DataTemplate>
                                <ContentControl Content="{Binding}">
                                    <ToolTipService.ToolTip>
                                        <ToolTip Content="My Tooltip"></ToolTip>
                                    </ToolTipService.ToolTip>
                                </ContentControl>
                            </DataTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </data:DataGridTextColumn.HeaderStyle>
        </data:DataGridTextColumn>
    </data:DataGrid.Columns>
</data:DataGrid>

  

You'll need to add this namespace declaration too

 

xmlns:dataprimitives="clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls.Data"

  

As far making it dynamic, i'm not sure what you mean by that.. you could bind the text of the tooltip to some value, or even handle the opened event of the Tooltip, grab the tooltip's data context and then based on that decide what to put in the tooltip.
