I shower daily like a person with real hair would (just wet, shampoo once a week), never had an issue. If anything, I just have to reattached sooner so the tape doesn't get gunky.

I was in bed, um, romantically, and rather drunk and I got busted, but it was someone I was dating regularly and they didn't care a single bit. If I recall, the last thing that was said was, "but it looks fantastic, right?!" - Of course the answer was yes.
