DD has dark hair. She is almost 15 and I noticed this week that the hair above her lip is growing quite dark and she has a bit of a moustache. She hasn't noticed yet, and before she does want to provide solution for her. and before someone else does. I'm fair so never had this problem. Needs to be low maintenance option if possible as she has very little spare time to visit a beauty salon but what's best option ... Waxing, threading, laser, ectrolosis?
TIA
