This 8 oz. bottle of conditioner is designed for use on wigs. We’ve tested it on our wigs and it works nicely. After shampooing and rinsing the wig, put a handful of the conditioner into a bowl of water, mix it up, and soak the wig in it. Work the conditioner mixture through the whole wig, and then rinse it off. It leaves the wig smoother and more manageable.
