M: Hello.
W: Hello, welcome to "Advice" radio program, what’s your name?
M: Jim.
W: What’s your problem?
M: Er...well I’m er...beginning to lose my hair. Er, 1 went to the doctor, but he just said there was nothing I could do about it. He said it was probably hereditary. My father was bald by the time he was thirty.
W: And how old are you?
M: Me? I’m twenty-eight.
W: And are you losing a lot of hair then?
M: Well, it comes out a lot when I comb my hair and you can see a thin part on the top of my head.
W: Does that really worry you, Jim?
M: Well, I don’t like it. It’s old, you know, looks old. I don’t want to look like a middle-aged man at twenty-eight. And I wonder if there is some special shampoo I should use, and if you could tell me one that I should buy, something like that, you know, to stop it getting worse.
W: Well, you know, Jim, to be honest with you there’s not really a lot you can do about it, actually, I’m afraid. I mean, baldness is one of those things that, in my experience, you just have to try to accept. Some men find it more difficult to accept baldness than others. There is one piece of advice, though, Jim, and that’s don’t try to comb your hair over the bald or thin patch. Whatever you do, don’t comb it over because that usually looks ridiculous. And the other thing that usually looks ridiculous is a man with a wig, that is, the false hairpiece. Don’t let anyone persuade you to buy one of those false hairpiece things, because they usually look much worse than a bald man. I actually think bald men can look very attractive. My husband is bald and I think it really suits him.
