What's the deal with the purple wigs in UFO? Although numerous attempts to explain a scientific purpose for the purple wigs on the female staffers at SHADO Moonbase have been proposed through the years (the most common being that they are anti-static wigs to prevent migraines), the fact remains that they were merely part of Sylvia Anderson's design for the SHADO Moonbase women's costumes and serve no functional purpose.

By the way, not just women wore wigs in UFO. After the first few episodes were shot, Ed Bishop wore a blond wig to prevent damage to his dark hair from repeated bleachings; Bishop kept his wig as a memento of the series and shows it off at conventions. George Sewell (Col. Alec Freeman) and Michael Billington (Col. Paul Foster) also wore wigs to keep consistency in hair stylings and lengths since the episodes were shown out of order from their original shooting.
