He noted that there were pounds of medical tape covering his hair, but the situation doesn’t look that cumbersome to me.
Of course, this also means that the underside of said tape is also covered with copious amounts of glue, and therein lies Cavill’s motionless struggle.
I don’t know anything about professional fantasy TV show wig removal, but it’s pretty clear from the photo and Cavill’s caption that it’s not any kind of a joy to experience.
