Vivien halo hair extensions are a simple, one-step method to achieve longer and fuller hair. They’re perfect for first-time users and simple enough to apply for everyday wear in just a few minutes. Halo hair extensions sit gently on top of your head, secured with a thin, invisible wire. If you have short hair, we do not recommend Halo hair extensions. Instead, we encourage you to opt for our clip-in hair extensions or hair weft.
