My niece that just graduated high school is a real earthy type and she's grown hers out. She showed it to me and made me touch it because she's proud of how soft it is lol. I told her good for her if it makes her happy, and don't let the shamers shame her
I wax everything, and once stuff starts growing out, I can't stand it. I'm quick to march myself to the salon to obliterate it. lol But hey, like you said, if she's happy with it, more power to her. :-)
