For more stubborn cold crimping, you’ll want to break out a wig steamer
. Use your wide tooth comb to smooth the fiber as you follow it with the steamer hose aimed at the area of concern. Allow the fiber to air dry and completely cool in the desired shape.
If your synthetic wig is heat-friendly, it can be styled using hot tools like a flat iron or curling iron and these methods alone will remove any unwanted crimps.
