I was in Istanbul recently, and we saw a lot of people (mainly men) with the classic tell-tale signs of hair transplants. The hair is shaved very short, and they always wear a headband, but with the 'new' transplanted hair clearly visible. Very straight rows of implants, with the skin very red. It was odd - once you noticed one, you were spotting them everywhere. I don't think it's exaggerating to say we must have seen dozens of men, all with the same giveaway signs - and that's just the ones who crossed our path. Not just in the airport, but around the city as well. We also saw a few women with the old plaster across the nose - where they'd had their nose 'fixed'.
Seems it's big business over there at the moment.
