I listened to your shirr which I enjoyed very much. I am learning Hilchot Shabbat and became interested in this subject when learning Siman 340 in Orach Chaim. There we are told that there is a prohibition of pulling out a single white hair even during the week due to Lo Yilobosh. I discussed this with my Rav and he believed that this is still the case (and may include dying hair). Having seen many mekorot and listened to your shiur I believe that we now live in a time when "metrosexuality" is acceptable and that male grooming is now not considered behaving in a feminine way whatsoever. I would be interested in your views on this. Regards and Shabbat shalom Barry Kleinberg London, UK
