These days there is no need to get her eyebrows done or her upper lip hair removed. By suggesting that it's necessary you will make her self-conscious. Many of my friends have daughters in high school who don't do any of that. They focus on school work, exercise and real friends who don't tease them for anything about their appearance. If and when she comes home and ASKS for hair removal or lightening, then and only then it's time to take action.
