How to visually unselect an item in a single selection ListBox?

I am using the first listitem in a ListBox to serve as a header row in a multicolumn ListBox but I can't seem to visually unselect it when the user selects it (since it's not actually an item I want to be selectable).

I have the change event set to this (have attempted multiple ways to unselect as you can see)

Private Sub ingredientsbox_Change()
If ignoreRefresh = True Then Exit Sub
If ingredientsbox.ListIndex = 0 Then
    ignoreRefresh = True
    ingredientsbox.ListIndex = -1
    ingredientsbox.Selected(0) = False
    ingredientsbox.value = ""
    ignoreRefresh = False    
End If

End Sub

The ingredientsbox.ListIndex correctly changes but the row is still visibly selected. Is there a way to make the selection visually go away? Thanks
