Are you sure you got enough laser treatments? It can often take up to six zaps-which is expensive, but we're talking life-long annoyance here. Those really work on the dark hairs (but not light ones) if you have light skin. Maybe you need to go to a different laser place, let everything grow in full thickness, (shaving only) and then zap away like crazy. Electrolysis is usually claimed not to be as effective as laser. I would SERIOUSLY recommend zapping as many as you can permanently before you go gray (laser won't work on gray). Once you zap as many as you can permanently, pluck AND shave the rest every day. Pluck to get rid of them for longer, shave daily to make sure none are glistening (they don't need to get that long). Six to twelve hairs is not that many, plucking and shaving take only seconds. But if I were you I would zap the dark ones while you can.
