halacha - Do Shaving Restrictions Apply to Bearded Women?

For example, if a woman were to have a beard, would she be permitted to shave it off with a razor or otherwise destroy it, or do these restrictions apply to both men and women?

Answer

Nope. It does not apply to women.

Source: Mishnah in Kiddushin (1:7)

‮וכל מצוה בלא תעשה,
‮בין שהזמן גרמה ובין שלא הזמן גרמה,

‮אחד אנשים ואחד נשים, חייבין;
‮חוץ מבל תקיף, ומבל תשחית, ומבל תיטמא למתים.

And every commandment which is a prohibition,
whether it is time-dependent or is not time-dependent,
both men and women are obligated;
except for "You shall not round off [the corners of your head],"
"You shall not destroy [the corners of your beard]"
and "You shall not become ritually impure for the dead."
