One of the main reasons I hear from people for not wearing hair: 'I can spot a bad hair piece a mile away.' That's only partially true. You can spot a bad hair piece a mile away---the good ones you never notice. The good ones are just too realistic to tell from your own growing hair. Here's an example of a bad hair piece on a celebrity. Even celebrities sometimes have bad hair pieces. This is Tony Curtis (bless his soul) and he did not take advantage of a good quality hair piece. His unit is spec'd out all wrong and the density is just not age appropriate. Color blend is bad, hair line is not exposed--nothing is right. I'll bet he didn't have hair that dense when he was 19. This is not a good example of 'state of the art' hair systems that are available today.
