Well, I'm thinking of writing a book but i sort of need to know if temporary hair extensions exist (i need this idea for one of my characters). Anyway, what i mean is that if hair extensions that are sort of like... wigs, actually exist. I mean, it would be something like extensions you could put on whenever you want to make extremely short hair look longer, way longer (like a bob hairstyle looking waist-length). Or does anything similar exist? Something that is easy to take off and put on by the wearer, something other than a wig? Please, if you could show me a picture and explain to me what you mean it will be very appreciated.
