I think it's just an age specific problem. My lace piece (I've been wearing it now for 11 months or so, day & night) is starting to look a little tired in the frontal area.
I just leave a few mil of stick-it tape extending past the edge so I can push the hairline into it. This stays pretty good for the 8-10 days bond I get.
I, like various long term wearers have said, don't strive for salon perfection everyday, I wear the wig, it doesn't wear me.
I wash my piece every 2 weeks if that (I don't gym or have an active lifestyle lol).
So to sum up my post....I'm rambling and not sure what point I'm making.
A hairpiece can last and be acceptable if you don't sweat much & stop fiddling with it all the time. Regards
