DL Trésors is a user-friendly mobile application that aims to simplify the connection between hairdressers and their potential clients. The focus is on improving the booking process, strengthening communication, and creating a seamless experience for both parties involved. The main features would include the creation of complete profiles for hairdressers, an interactive booking system with real-time notifications, secure online payment management, integrated messaging, a rating and feedback system, push notifications for promotions, and an intuitive user interface. Before launch, extensive testing should be carried out to ensure a smooth user experience, and continuous collection of user feedback should help improve the app based on the actual needs of users.
