A Bachur who normally tries b’n to avoid haircuts the entire Sefira and also on Rosh Chodesh, like the Arizal, may he take a haircut this coming Friday, Rosh Chodesh Iyar, in order to have a fresh haircut L’kavod the new Z’man and to be able to fit in better with the other bachurim in his Litvishe Yeshiva. Is Hataras Nedarim necessary? Can it be done before Chatzos (midday) on Friday?

Mishna Berura (493: 2) permits in this special case when it is Friday, Rosh Chodesh Iyar to shave in honor of Shabbos. Horav Shlomo Miller’s Shlit’a opinion is that it can be done even before Chatzos. No Hatoras Nedarim (absolution of vows) is necessary
