I was sick a couple of years ago and lost a lot of hair. Fortunately it did grow back in again (really curly for about two years...weird), but for about 8 months I was REALLY stressing about it. It bothered me enormously. I couldn't shut up about it either...which ...ugh, I felt like a fool. Anyhow, hair can be a huge issue. I now wonder if I'd have been better off getting a wig or a hair piece so that I could just stop thinking about it all the time.
It all depends on what you feel comfortable with. You look lovely, with or without hair.
