ShampooSalesAgent is a specialized conversational AI agent designed to guide users through personalized shampoo selection and boost sales performance. Leveraging LangChain to orchestrate GPT-powered dialogues, the agent asks targeted questions—such as hair texture, scalp sensitivity, fragrance preference, and styling goals—to gather user profile data. It then consults a configurable product catalog to generate tailored shampoo recommendations, complemented with upsells for conditioners or specialized treatments. The system logs interactions for analytics, supports follow-up clarifications, and can be hosted as a web widget or integrated via API on e-commerce sites. By automating the advisory process, brands can deliver 24/7 personalized customer service, increase conversion rates, reduce support costs, and drive revenue growth.
