Getting a haircut and shaving are generally forbidden during Sefirah (the counting of the Omer). Shaving is permitted by some on Erev Shabbos, (Friday), for the honor of Shabbos. So are there any similar rulings for getting a haircut?
I also heard that if someone tells you, "You're hair looks disgusting!" then you can get a haircut regardless of the day of the week. Is this true?
