I'm 38 and my piece is 60% and it is really full head of hair. I have a 55% graduated hairline. The stock graduation is about 1" and I have them graduate mine for only 1/2". I have good sides and back and because I look much younger than I am I can pull off this density. You can't see any of my scalp except in my hairline and my crown but there's enough of my scalp showing that it looks natural.
