You just need to be aware of a few simple things and it is really quite easy. Your hair system is cut hair and not growth hair so it is a little different than your own hair. It does not receive any protein or oils from your scalp like your own growth hair does. The only oily build up is from the products you put on for styling and conditioning. For this very same reason, cut human hair if not cared for properly has a tendency to get dry. This is not a problem with proper product selection and use. Follow these suggestions and you should experience no problems.
