A toupee can stay on for up to 4 weeks with the soft bonding application technique. However, the time it stays on depends on a few factors. For instance, some people prefer to take off their toupee before bed and wear it every other morning. Also, the toupee could come off a little faster if your scalp is often oily. That is why it is better to exfoliate and cleanse the scalp before wearing it. Another factor could be due to sweating or exercising a lot. You may want to take it off and wash it frequently.
