Demonstrate the hair product to the customer and work this to your advantage as they wouldn’t get this service if they had purchased the product online. You can allure them through the sense of smell, see and touch. Use this strategy while giving your client the service with that exclusive product. For instance, if you are massaging their head for example with hair cream, show the client how fresh and soft it is. Make them feel and smell the product so that they remain in the mindset of the product throughout the time at your barber shop. Ultimately, clients will return again and again.
