Question:
I'm a married woman (almost a year), may I clean my eyebrows and shave my legs during the 9 days?
Answer:
Your question really applies to the three weeks and not only to the nine days. A woman may pluck her eyebrows during the three weeks, as it is not considered cutting hair. Regarding shaving her legs, if it is needed it is permitted.
Best Wishes
