Hair Removal for Men - Instructions

Is it permissible for a man to remove hair with a laser, and if so, where?

Hello 

I am attaching an answer written according to the instructions of the Gaon, Rabbi Avraham Fried, shlita

Hair removal for men:

Armpit and pubic hair:  Initially, it is advisable to be stringent and not shorten at all [according to the opinion of the Rashba]. However, the main  law permits shortening with regular scissors, ensuring that noticeable hair remains  [according to the Shulchan Aruch].

Other body hair: It is permitted to shave with scissors like a razor, [meaning it is allowed to achieve a result similar to a good electric shaver],
but removing with wax and laser is forbidden

Facial hair: Anything that is not part of the peyot,  initially, it is advisable to be stringent and not remove  with laser and wax. However, by the main law, there is no  prohibition.

Yoreh De'ah, Siman 182, Se'if 1 and Darkei Teshuva there, Sif Katan 1, d
Regarding hair on the rest of the body, it is written in the Shulchan Aruch there that in a place where men also remove hair, if he removed it, 'he is not punished'. And the Rema wrote that even initially it is permitted, and only the pious avoid it everywhere. Some wanted to say that in our time, when non-Jews remove body hair with laser, and even Jews who do not observe commandments remove, and even some who observe Torah and commandments have permitted this (not according to the instruction of a sage), there is no prohibition of 'not wearing'. However, since the Pri'sha there is uncertain, saying [and this is brought in the notes of R. Akiva Eiger there] that only if there are kosher Jews who remove, there is no prohibition of 'not wearing', therefore it is forbidden to remove body hair with laser and wax.
However, removing facial hair with laser and wax, where there is a certain community observing Torah and commandments that permits this - it is not permitted initially, but one who is lenient has what to rely on.
