If Abrams was wearing during the OJ trial back in 94 then he would have to be suffering from typical male pattern baldness. The first time I remember seeing Abrams was in 2003. I was posting on another hair forum at the time and someone mentioned his obvious piece which led to a discussion. I hadn't seen Abrams since then until the Jodi Arias trial. I noticed how natural his hair looked and assumed he found a much better alternative. Seeing him recently hosting Nightline I found it hard to believe that was a system he was wearing. His hair looks incredibly natural which got me wondering if he had transplants. When I googled his name the word cancer came up which I didn't initially follow up on.
I read where Keith Olbermann joked about him being bald in 2010 (article below) so maybe he is wearing a hairpiece. I followed up on the cancer report and he did have testicular cancer in 03 and chemo does cause hairless which would explain him wearing a piece back then. The article below has comments from those who were surprised he wears a piece so maybe he does wear.
