Guys, I received my first system today and need some advice. First off the piece is a lot darker than my hair is, so can the piece be dyed to something closer to my color? Also the wave is kinda curly, does this go away? I ordered the piece slightly longer so when I go for my cut in I am hoping she can just cut some curl out. I tried it on, of course no bonding or anything and I look like one of the Beatles when they first hit America, so hope it looks more natural when I get it cut in because if not I would prefer to keep going with wearing a baseball cap. So if you guys can help with these questions I would much appreciate. I'm kinda bummed out with the piece right now but hoping you guys had some same issues when you first received yours and after cut in we're happy. Thanks!

1) Can I dye the piece?
2) Does curl ease with either washing or product?
3) Should I use a knot sealer before my cut in?
4) Should I wash before cut in?
5) How do you tell if knots were bleached?
