This has been on my mind lately. My eyebrows are Ok, just tweeze every few days.
But... in the past few months my "mustache" has gotten thicker. It's blonde, but there are now rogue dark hairs appearing maybe once a week. When I look closely, I notice that I actually have a nicely shaped beard, but no one can see it, since it's blonde and thin peach fuzz. I am thinking of getting the upper lip waxed, but I am not sure if I have to let it grow a bit. I've been trimming it with baby scissors and plucking out the rogue dark hairs. Ouch for that. My only experience with waxing is the bikini area and I hope that if I get the upper lip waxed that I won't have the same irritation afterwards (I think that is mostly caused by clothing irritation). I would consider laser treatments, but I read that post that said it doesn't work so well for light hair.
