In the hairdressing industry, consultative selling treats customers as friends and hairdressers as their consultants, helping customers find the best products and solutions for their hair problems. This approach is different from traditional sales, which focus solely on achieving product sales. Consultative selling can establish a relationship of trust between hairdressing shops and customers, leading to increased customer loyalty and repeat business. Through personalized product recommendations based on a careful study of the customer's hair, hairdressers can enhance the friendly relationship between the customer and the salon, making the customer a regular customer of the salon.
