M: I need a haircut. But you look pretty busy today. Do you have an opening for me?
W: Yes, we do. I can cut your hair right now if you like. Do you need a shampoo too. or just a haircut?
M: Just a haircut. I washed my hair this morning.
W: Alright. (22)I will have an assistant wet your hair. Then I can start. Please step over there. How would you like your hair cut today?
M: Well, I had a haircut eight weeks ago. So my hair is pretty long. However, I want the same style as the last time.
W: I recommend you leave it a little long on top. But we should take in the back and sides a bit more. That’s more fashionable now.
M: Alright. You are the expert. I’m happy to have your recommendation.
W: And do you usually part your hair along here?
M: Yes.
W: Alright, I know just what to do. (23)Your hair seems quite dry, you know. And I see some split ends.
M: (24)Yes, 1 know my hair is quite thin. It runs in my family. Everybody has very thin hair.
W: The problem is the split ends. They make your hair look even frizzier (卷曲的).
M: I don’t know what to do with it.
W: Well, it’s easy. Don’t blow-dry your hair for so long after you shower. (25)Let it dry naturally, then you won’t get split ends.
M: Oh really? I will try. Thanks.
