is it normal that i have hair on my chin

Yes, some women get superfluous facial hair on their chins. When I was about 19 I only had one and would just tweeze it. Now, I at 44 I have significantly more and I tend to still use tweezers but sometimes I wax or use an electric epilator thingy. I would like to get laser done at some point. It's a little expensive and slightly painful but very worth it!
