OK, so I'm much younger than most of you guys, and I still live at home with my mum, dad, and younger brother. What I need to know is, will I be able to wear without them knowing? I've been trying to tell my parents for over a year now that I'm losing my hair, but no matter what I say they just won't listen. I have absolutely no idea how they would react if they found out I was wearing hair, and I'd prefer to keep it that way. It wouldn't matter as much if my younger brother knew, but again I'd rather keep it to myself, it's just easier, less embarrassing and then there's no chance of him letting it slip to anyone. I'm hoping to get a full cap that looks something like this:

A few questions:
- How often will I need to take it off, wash it and re-attach?
- When I'm washing it, how long will the piece have to be off my head for?
- Will I always need to have a spare piece handy, or will I only have to get one when I've been using my current one for a little while?
- When I get my piece, since it will be a full cap will I still need to go to a hairdresser and get it cut in? Or can I just attach it straight away?
