Throw my advice in the trash?

Fact: the piece is way too far down on his sides.

Fact: his hair is cut short on the sides, and his density is not 50%. I cut hair for a living. He is definitely not 50%. He will be able to get by with a 65% density, or in that ballpark, with no problems.

Fact: he needs a professional to blend his hair and make it look right. Some of you guys have figured out how to cut your hair at home, but for those that can't, just go to a barber or stylist. Most barbers are experts at blending and fading. And most have worked with a hairpiece at least once in their life.

My advice still stands. You don't need a piece that goes that far down on the sides. And you don't need 50% density. 50% is way too thin.
