In the long run, that is a problem. “People continue to age. Suppose you fill in the hairline of a forty-something, to everyone's satisfaction. But many years later, that man may lose his hair on top. If there is still hair capital, you can fill it nicely with a second transplant. If that capital is gone, that man will have an intact, transplanted hairline for the rest of his life, but with a bald top. I must not tell you: that looks very strange.” How can you avoid such a thing? “The patient must be well informed and the doctor must calculate properly: how much hair is there, and can the problem area be completely filled with it? You can do wonderful things with a transplant, but I have to say to 30 percent of the men who come to me: 'Sorry, you are not a good candidate. Within 10 years you will have holes and pimples.' A good doctor says something like that, but unfortunately there are cowboys on the market. A full transplant at Feriduni, as well as at other reputable doctors, costs an average of 8,000 to 10,000 euros.
