COVID-19 vax sparks rare Marie Antoinette syndrome: case

One unlucky patient had sudden hair loss before it grew back with a snow-white appearance

Both COVID-19 diagnosis and vaccination can be a shock to the system for many, but for one unfortunate man it was enough to turn his hair white.

US and Canadian doctors say the 44-year-old patient developed two separate acute hair-associated events — alopecia areata followed by canities subita, which is also known as Marie Antoinette syndrome.
