During a visit with David Letterman last month Tom Jones proved he still has the voice - but what most people were left singing about was Jones' fuller, thicker hair.
Jones famously decided to stop dyeing his hair two years ago, saying he was ready to age naturally. But this new 'do' suggests that while he might have accepted his gray hair, he isn't quite ready to embrace hair loss.
Jones has yet to comment on the speculation, but from looking at the pictures, it appears he's embraced hair restoration treatment. It's possible he's using a multi-therapy approach, such as Propecia and Rogaine, and he might also have undergone hair transplant surgery.
