I think I'm going to shampoo my hairpiece for the first time soon. I picked up some of that L'Oreal shampoo and also the conditioner that Snipe recommended a few weeks ago. My four questions before doing this are:

1) How do you apply shampoo on a hairpiece?

2) How do you apply conditioner on a hairpiece?

3) How do you rinse?

4) How often do you use shampoo and conditioner? (I've read everywhere from daily to once every 3 weeks.)
