One of the important things for undetectibility is to have good bland between hairpiece and your own hair. I am assuming that once you get your initial cut-in with your hairpiece, it will be good until it is no longer wearable. But how about your own hair? I am concerned that once I put on my topper, growth of my own hair may "give it away" after couple of weeks. I have medium length hair and it tends to grow at a decent rate. Do I have to go to the stylist every couple of weeks to have it trimmed?
