Q. Can a man trim his eyebrows if they are unruly and get into his eyes? What if his wife asks him to do it?

A. Shulchan Aruch (Y.D. 182: 1) rules on the prohibition to remove bodily hair growth. However Mordechai (Shabbos 50: 327) permits in cases of great discomfort or pain. Avnei Yoshfe (Y.D. 91) accordingly permits trimming eyebrows, adding that women pluck those hairs and do not usually trim them.

Nishmas Avrohom (Y.D. 182 p. 140) quoting Horav S.Z. Auerbach Zt”l that permits the removal of embarrassing excessive hair between the eyebrows. Similarly Levush Malchus (4: 13) permits trimming with scissors, but not plucking with pincers. (See also Chevel Nachalaso 13, Birchas Yehudah (Y.D. 9) and other Poskim quoted in their notes for comparable opinions. See also Bava Kama 117a, that Rebbi Yochanan had very long eyebrows that covered his eyes)

Horav Shlomo Miller’s Shlit”a opinion is that the eyebrows can be trimmed for the sake of one being able to see properly but not with the exactness and meticulousness typical in women’s facial treatment.
