We purposed to enhance the accessibility and accuracy of alopecia counseling by proposing a retrievalaugmented generation (RAG) chatbot built on a large language model (LLM). The system integrates curated domain knowledge and empathy-oriented prompts to generate reliable and patient-friendly responses. A domain-specific dataset of approximately 1.33 million words was organized hierarchically and indexed with relevant keywords to support retrieval precision. To evaluate performance, 100 representative queries across five counseling categories were answered by both a baseline LLM and the proposed RAG-LLM. An external domain expert rated each response on factual accuracy, hallucination, clarity, and coverage. The RAG-LLM achieved higher factual accuracy (95% vs. 70%), lower hallucination (3% vs. 25%), and improved clarity and coverage (4.5 vs. 3.3). Statistical analysis confirmed the significance of these differences. The results demonstrate that platform-native RAG implementation can improve factual reliability and communication quality without external retrieval infrastructure, providing a practical framework for developing trustworthy, empathetic, and accessible digital health counseling systems.
