Dancing,
According to the ones who permit פאה נכרית, they are specifically very clear that it indeed does look like your own natural hair and is permitted.
In my opinion, differentiating is pure ignorance. The very ones poskim that all klal Yisrael are following are the שלטי גבורים, מגן אברהם, רמ”א, א”ר לבוש, and others , the specific original shayle posed was, if a women is permitted to wear her friends hair” and they ruled YES. The ones that prohibited (באר שבע) did not permit ANY wig at all.
You can claim that any hair or wig needs to be modest, but to saying that it needs to look like unnatural etc. That goes against the very foundation of it’s original ruling.
In other words, you either cannot wear any wig at all or wear any modest wig.
