I to had a friend about 65 years old and you could spot the bad hairpiece a mile away. Like you mentioned a TOTAL pitch black hairpiece. It was actually the only black hair on him. Beard and eyebrows were white. The density must of been 200%. Like you it did not even look like hair until you actually got close enough to see that it was hair and not a helmet. I was so embarrased for him. Does he or his wife not notice?. Anyways then went in for my monthly maintenance and started talking with my stylist and found out he was a client of my stylist. I found out that the stylist had to fight tooth and nail to get him to lower the density a little. He actually orders his pieces so dense that it is impossible to see any of the scalp at all. Just to let you know , I actually came very close to telling him discretely that he should add grey, lighten up on the black and cut the density about 60%. Just my opinion.
