If you can afford it, why don’t you suggest a spa day type thing for her as an adultish treat. Get her hair done, her nails done, and—as part of the day, only if she wants—her eyebrows cleaned up a bit. When you take her, talk to the ladies to make sure they know you only want them cleaned up and maybe for them to show her what to do. If you can’t afford a day out, suggest the same thing. But at home. Facials, nails, eyebrows. Um, maybe not a haircut, but you know, the other stuff.
