If your DataGridColumn is a Template then you need to change its Template in code.

    var template = new DataTemplate();
    template.VisualTree = new FrameworkElementFactory(typeof(TextBlock));
    template.VisualTree.SetValue(TextBlock.TextProperty, "New Header");
    dataGrid.Columns[0].HeaderTemplate = template;
