A hair preview is a way to see how a certain hairstyle or hair color will look on you before actually committing to it. It can be done through virtual try-on tools, where you can upload a photo of yourself and see how different hairstyles or hair colors will look on you. Hair previews can also be done in person at a salon, where a stylist can show you a sample of the hairstyle or color you are considering. This allows you to make an informed decision and feel confident about your choice before making any changes to your hair. **
