I haven't really payed too much attention to Tico but he may have had a hair transplant. I remember he was receding quite a lot around Lost Highway I think and then around The Circle his hairline looked much better.

There's no way Jon has had a hair transplant. It's fairly obvious (if you look for it) that his hairline has been progressively receding over the past 5 years, so I can almost say with certainty he hasn't done anything in that regard. I also really don't think he's done anything in terms of botox or facelifts. He's just blessed with ridiculously good genetics and clearly lives a good, healthy lifestyle which keeps him looking good.
