I say, and with God's success: It is permissible for a woman to shape her eyebrows as long as it does not reach the level of temptation or involve beautifying herself for non-mahrams. She should take care of herself for her husband and not deviate from the usual appearance of women in eyebrow shaping, so that it does not cause excitement or temptation, and her appearance should be like that of other women. And God knows best.
