- – Q. Kevodo Shlit”a.
As we just ended the mournful period of the Three Weeks for the destruction of the Temple, and now we can take a haircut or shave for those who avoided it before, since today (on 2025) is Monday, is it better to wait and shave for Shabbat on Friday?
A. A main issue is how much you require the hair-cutting or shaving for your regular daily activities. If possible it is indeed may be better to wait and do it Likvod (for honoring) Shabbat.
We must mention that indeed the Sefer Minhag Tov and others mention this tradition as being special for Shabbat Nachamu.
Horav Kalman Ochs Shlit's maintains that he can shave again lkovod Shabbos
