There are several known causes that contribute to tangling of the wig especially at the back nape area. Leaning against a pillow, chair or sofa may cause friction that can over time cause some tangling and damage to the hair. The use of a satin or silk pillow case and throw for the furniture will help to prevent this from occurring. It is also a good idea to not sleep in the same prosthesis that you will be wearing during the daytime. Sleeping in the prosthesis each night will reduce the life and quality of the hair. A possible solution would be to use the older of the wigs for sleeping as you begin to use a new one for the daytime wear.
Heat can be another source of damage to the hair. When using styling tools you should never use the hottest setting to dry the hair. The cool or warm setting is preferred and will allow you to maintain the quality of the prosthesis for a longer period of time. The use of cool or luke warm water to wash and condition the hair is preferred. Professional salon quality shampoos and conditioners are suggested for weekly maintenance. The use of curling irons and flat irons can damage the hair and will cause the hair to dry out excessively. Allowing the hair to air dry and the use of rollers will help to protect the condition of the hair.
Caution should be used when opening and removing items from the oven. The first blast of heat from the oven door can be damaging. Standing back a bit as you first open the oven door is a good preventative measure to take even for naturally growing hair. Sitting too close to a fire at the fireplace or cooking or standing too close to an outdoor grill might possibly cause excessive dryness and damage to the hair.
If you are traveling, be sure to not leave any extra prostheses in the car during the summer months. The temperature in the car becomes extremely high. Extra prosthesis that you will take on an airplane should be taken as a carry on since temperatures are unpredictable in the luggage compartment of the plane.
