This varies from person to person and how well the Hair Extensions are treated. We recommend that you properly store your extensions back in their original packaging when you are not wearing them to maintain their style, shape and bounce! Our Premium Synthetic Hair Extensions are better suited for occasional or weekend wear, with a typical lifespan of 3-4 months. With our 100% Human Hair, you can expect a greater longevity as they are made from a different non-fibre material.
