Why does the person who washes your hair in the hair salon ask if the scalp itches?

I am an apprentice. It's simple. First, I'll ask you when it's almost time to wash. Shampoo: Does the scalp still itch? You: Still itchy, behind. Yes, right there. (End) Shampoo: It still itches there. You: It doesn't itch anymore. Shampoo: Oh. Ok, let me develop it for you. You: Mm-hmm. Shampoo: Is this water temperature ok? You: Hmm. Just right. Second: it's almost time to wash. Let me ask you. Shampoo: Does the scalp still itch? You: Still itchy, behind. Yes, right there. (End) Shampoo: It still itches there. You: I'm washing, so soon. Shampoo: Oh, I'll rinse it for you if it doesn't itch. You: .......... Shampoo: I washed it. You: That's too fast. It takes a long time to wash it. It doesn't feel clean Shampoo: .......... (while flushing) You: The water is very hot (the water is very cold) Shampoo: Oh. You: It's still hot. Shampoo: Is that all right? You: ............ washes her hair, cuts her hair and goes out. You: Why does this man wash his hair? He just burned me to death (omit 200 words below)-_-||||| You know. Please adopt
