How to promote shampoo in hair salons

I used to do a one-month promotional shampoo, which was from Meiwang. I sell it in a supermarket. I don’t know where the original poster sells it. But as long as you see the customer watching, you go up to answer the question. For (lady), first say hello, would you like to see the shampoo? Do you think you need nourishing and moisturizing your hair? Or to stop dandruff? Still wait. If she answers, you bring the corresponding shampoo. If she just looks at you and doesn't answer, say that your hair is a little dry. You can use this nourishing one, which can have very good results. (Men) Hello sir, which shampoo do you need? I'll get it for you. What do you think of this one (get the one for men) and tell him how it works. (Elderly) Mom, uncle, what kind of shampoo do you need? The recently released one is particularly useful. Many ladies and gentlemen buy this product from us. It is an all-in-one formula that not only solves your dandruff problem but also nourishes your hair. And it's purely plant-based and won't harm your scalp. There are many repeat customers. You try it. Then give it to him. He might take a look. Then you said remember to do some publicity for us after you use it. The effect is really good. Anyway, you basically have to rely on the customer's expression to speak, and you can't talk about the effects endlessly. Will be disgusted. Do you understand? hehe. I wish you success in your career.
