The less abuse the hair replacement receives, the longer it will last. This does not mean that you should stop doing the things that you enjoy such as walking, running, swimming and just enjoying the outdoors.
You must understand that hair fades in color, especially on a system that is not growing and replacing itself. Hair loss also happens, just as it does in your own natural growing hair.
You will need to have your system colored from time to time as the hair fades and to keep it looking like your natural hair. Hair will have to be added to replace hair that has fallen or broken off to keep the density of the system looking as natural as your own hair.
