Can one pluck hairs from ones face, or sideburns? Does it matter if its ingrown?
Plucking facial hair in a way commonly done by men as well as women is permitted. It is forbidden for a man to pluck out white hair from a colored beard [Y:D 182:6]. Plucking hair from the sideburns should be avoided as according to some opinions this is a problem of הקפת הראש, removing sideburns. See Gilyon Hashas Shavuos 2b, and Shu”t Chasam Sofer Y:D 139.
