When your system arrives in the mail, you will need to first take it to a hair stylist to have it cut, thinned and blended into your own hair.
Clean your toupee with a mild shampoo, use cream type Conditioners that do NOT contain Lanolin, polymers, or heavy oils. Use leave on spray conditioner also to keep the toupees soft and pliable. Use the deep conditioner once per week to prevent dryness and use the Detangler spray to keep the hair from tangling. And never use any alcohol based styling aids as they will dry your  toupees.
