I used to be overweight. Not terribly so, but I was pretty pudgy. When I was still pudgy I started growing hairs on my chin and underneath it (mostly underneath my chin). Well, I lost a lot of weight and am now slim, but I still have the same hair problem. It's like it's there for good for me. It's not soooo bad though. I just have to check it a couple times a week.
Arg...I hate hair in unwanted places!
Do you have a LOT of hair on your chin? Do you use tweezers for it? I have some good tweezers I keep on hand.
