Post op Chest hair loss?

[PSC0002]

I am 3 weeks post op tomorrow.  Happy to report minimal pain and bruising at this point, but some swelling without the vest on at the nipple line.  But that's what I expected.  However, I have noticed that when I take off my shirt to shower that there are a few more chest hairs on my shirt than I've ever noticed in the past.  I'm not an especially hairy guy, I would say perfectly average.  I don't know if I was caused by bruising, compression, or the fact that I've been wearing exclusively Under Armor shirts under my vest at the suggestion of my PS. 

I wouldn't say that this was a problem per se, but I did find it a bit peculiar and wondered if anyone else experienced this.

Thoughts?
