What did not the man require?

M: I’d like a haircut, please.
F: Would you care for a shave and a shampoo as well?
M: No, thanks. A haircut will be just fine.
F: All right. How do you like your hair cut?
M: Don’t cut it too short on the sides and the back. Just trim it a little.
F: How about on top?
M: You can thin the top out a little, but just a little.
F: Very well.
M: Say, my hair is kind of oily, and dandruff bothers me very much. I’ve tried several shampoos in vain. Can you recommend me something effective?
F: Well, have you tried Head And Shoulders? It’s supposed to be good for the dandruff.
M: I’ll try it.
F: And you can try Vidal Sassoon’s hair tonic. It’s used after you wash your hair. It’ll keep your hair clean-looking and oil-free.
M: I’ll try that, too. Thank you, barber.
F: It’s done. That will be five dollars and thirty cents.
