People try on virtual hairstyles to test out different cuts without actually making the change. Uploading a personal photo shows how the style looks on the individual instead of a model with a completely different face.
People sometimes have difficulty imagining how hairstyles would look on them. A style might look great in a photo of another person, but it looks completely different on someone with different facial features.
Virtual hairstyle websites allow the user to upload a head shot and put different hairstyles on the picture. By testing out several different styles, the user gets a sense of the cuts and colors she likes on her face. She can try endless hairstyles without committing to any major changes on her own hair.
