There's not a lot of updating to do about hair after you've shaved it all off.
I thought a buzz-cut might work, but instead of long hair falling out, all it accomplished was short hair falling out. Plus, I had a splotchy, uneven "chemo-head" that didn't look attractive or healthy. So my wife helped me shave it off.
In the space of less than a week, I went from a full head of hair to looking like I'm auditioning for the "King and I" at the Kettleman City "holiday spectacular" dinner-theater.
As they say, the show must go on!
