How to chat with a 2-3-year-old male customer who washes his hair in a barber shop?

Talk about the weather, work and so on. Never recommend the dyeing package, nursing discount, card application and so on again and again. I believe most people are disgusted with this. It's nothing to recommend it. If he is really interested, he will follow your words. If he is not interested, don't mention it again. You can ask him if he has a girlfriend or wife, and get a card to use together. If you are not interested, forget it. Don't repeat it. It's best to ask him what he wants when cutting his hair, such as how much to cut and how to trim it, so as to avoid conflicts when he finishes cutting.
