A lot of celebs have had subtle work done, when starting to lose hair. Some very good examples, Bono, Christian Slater, Costner, Sting (I think he's had work done), U2's Edge had one of the pluggy ones in the 80s, but I often wonder why he never got this fixed and opted for a hat. Probably loads out there. No stigma anymore about getting a HT done. Celebs going public about it, helps as well.
