There does not appear to be strong public confirmation that Tracy Townsend is wearing a wig, or why she would be wearing one. That matters.

What the searcher wants

Most people typing this query are reacting to a TV appearance and trying to explain a change in hair shape, volume, or texture.

What can be said responsibly

TV hair can change for many reasons: styling, extensions, lighting, protective styles, medical privacy, personal preference, or a wig. Without a direct statement, it is only speculation.

Bottom line

If Tracy Townsend has not publicly explained her hair, the responsible answer is simple: we do not know. A visible style change is not proof of a wig.
