Tea Tree oil will also do the trick.Once you have your hair products, it’s time to move on to step #2. The second step of reviving your dried-out hair is to brush it. Brushing helps untangle and makes cleaning that much easier.Start at the ends as you make your way to the cap of the wig. Once you’re satisfied, it’s time to wash it. Be generous with the shampoo depending on the condition of your hair.After a thorough wash, repeat the same routine with a conditioner then oil it after rinsing out the conditioner. If you’re in a rush to dry it, you can always use a blow dryer, but make sure it's in the cold air setting.
