Prepare your wig before sleeping
Too much friction will damage your wig. To reduce friction while sleeping, you can braid your wig or put it in a ponytail and pin or tie it into place. Then, try to warp your head with a silk or satin scarf.
Use a silk or satin pillow caseBesides preparing, you can also use a silk or satin pillow case. This may also reduce matting, tangling and other friction related issues.
Brush your wig thoroughly in the morning
When you wake up, carefully yet thoroughly brush or comb your wig to remove any knots that may have formed overnight. Don’t be lazy and just let the knots on, the knots will be very difficult to move. If your hair looks flat in some areas, use a little water, leave-in conditioner or wig spray and gently fluff it.
