Harav Avraham Adas Mechaber Sefer ‘Peas Z’kancha’ and ‘Arbaas Haminim Lemhadrin’ from Eretz Yisroel, presented a shiur on the halachos of haircuts according to Halacha.
Rav Shmuel Meir Katz was in attendance along with many local Rabbanim. The shiur was delivered in the Bais Havaad.
R’ Adas discussed the halachos that arise even when giving/receiving a simple haircut
In Eretz Yisroel, Rabbanim recently put out a Kol Koreh and gave shiurim for barbers to ensure haircuts are done properly – Al Pi Halacha.
Many communities even launched a kashrus ‘agency’ free of charge to certify that it’s barbers attended and learned the halachos of haircuts.
