I wouldn't draw attention unless daughter brings it up first.
"The care and keeping of you" is a great book and place to start the conversation.
By the way, thanks to those of you who recommended that book .. another tidbit I picked up on here :)
ETA:
Just thinking .... I wouldn't let her see you fuss about your own hair, as in a bad way. I've made sure not to do that with my own browns in front of my kids. My kids all inherited my bushy brows. They're not quite a unibrow but they are definitely thick.
I asked a question not long ago on how should I best deal with them as I've been plucking them for decades. I finally bit the bullet and went in to have them looked at and be advised on the next step. The esthetician (best one in city according to reviews) told me I had great brows and told me to simply trim them. So that is what I've been doing. I am embracing the thick brows. I could have saved myself years of agony.
I think sometimes we send messages to our kids that such and such is not good - when really we just have our own issues with our bodies. I get that a unibrow is not the best - however, I think times have changed somewhat. One of my kids still gets rid of his, but the others have just accepted theirs. One kid had a kid poke fun, but I checked out that kid's brows when I last saw her, and she's sporting a big one herself - so some of that is insecurity.
As for deodorant, and zits, etc. Yes, I definitely just produced deodorant and special soaps, etc. when I saw fit. That - I would just introduce (around same time I gave them books) and we talked about 'hygiene'. But things like their facial features, and brows etc. I wouldn't even let her see that you have a concern over your own. I saw my mother yank out her brows, and my older sisters which is why I picked up my pair of tweezers at 10 - is what I'm saying.
