That's pretty much what I've had over the past week of being sly. Pretty much zero reaction. I've had a total of two comments; so I'm pretty much assuming most people either haven't noticed or cared. I did keep my hair quite short (beard trimmer with no guard) for a number of years, so it's likely most didn't even notice. (Which tells me I already looked more bald than I thought
)
The first person to notice (and say anything) was my four year old son, but that wasn't until 3 days after I'd started shaving; the other was a friend just yesterday. My wife still hasn't said anything on the subject, so either she hasn't noticed or doesn't care about it...
My son was cute about it. He just got a bit of a silly grin and said, "Dad how did you get your hair like that?"
