regarding your answer in http://dinonline.org/2017/11/12/laser-hair-removal-for-man/ the shulchan aruch is clear we do differentiate between different methods – tar and misparaim kein tar – no where do we find the result of these 2 is different
many poskim hold we dont judge by chilonim עי’ בפרישה, סימן קפב, ובחידושי רע”א, שם; שו”ת מהרש”ם, ח”ב, סימן רמג; אך דעת הגאונים היא שדי בדרכם של גויים של אותו המקום, כפי שהובא באוצר הגאונים למסכת נזיר וכמבואר בשבלי הלקט, יו”ד סימן מ; ועי’ עוד בשו”ת גינת ורדים כלל ו, סימן יב
– even if rav elyashiv was maikel on these 2 points – [which is very questionable – the source quotes a kovetz with piskei halachos bal peh – usually very unreliable – you could check with his many talmidim – r morgenstern etc.] – we would have to judge each place – is it common to shave legs in lakewood, in yerushalayim? laser hair removal is unheard for men anywhere- meaning a complete women’s grooming-
this is a real chashash deoraisa – maybe he could trim a little with a trimmer – we are not talking about major issue – hairy legs for men… there are many people who will see this and think all is mutar – which is basically what you are saying, so plucking white hairs is also mutar…
definitely check with your rabbeim on this one [and a talmid of r elyashiv] – it comes across as a shtikel psak tamuah
You have a valid point that the mameh mikomos of the answer weren’t clear enough, so i will explain myself. The reason for the heter is not because of the amount of people that shave body hair, whether they are gentiles, non religious or frum, (although it might be a heter on its own, but it is controversial). I was also not coming from an angle of where it is or isn’t the minhag. The heter is because of the Rashba, and Mordechai, brought in the Darcei Moshe Y:D 162, and in the Mechaber Seif 4, that when it is being done for refuah or to iliminate an embarrassment that it isn’t considered lo tilbash and it is permitted to remove. Also see Nishmas Avrohom Y:D 162-6 regarding dying hair for someone who has a discoloration of the hair, that he brings R’ Eliyashiv In Kovetz Teshuvos 3-128, that shaving hir for a man is a takana d’rabonon, ( see Bais Yosef 162-6, that this is the shita of the Rif Rambam and Rosh) and there was no takana bmakom tzar. Meaning that it is muter to remove the hair. What I meant with bringing R’ Eliyashiv, is for the point that he says regarding electrolysis, that once it is permitted to remiove the hair, it doesn’t matter how it is done, because the end result is the same in the way it looks. The person that quotes R’ Eliyashiv is Hagaon R Mordechai Gross shlit”a in Tel Talpios, where he write the question that he himself asked R’ Eliyashiv. I consider him to be reliable.
