Hi,
On my way to work this morning,and there was a guy walking 20-30 metres away and you can spot the piece.I know we can discuss at length this issue of dectectability,but this was so obvious it would be embarrasing.These are the factors that i believe made it obvious :-

1.He was an older guy probably about 60,and the hair was totally black,coloured black without any grey.I think grey is very realistic as you get older on the piece.

2.Very high density,looked like a helmet.Correct density is important depending on your age,less is more.

3.Unnatural looking hairline.Looked like it was drawn with a marker pen.I think a lace hairline correctly applied can be pretty much undectable .

4.Back of the piece near the nape of the neck the hair curled up and out,not back into the neck,or flat to the neck

I havent posted this thread to make fun of this guy at all,just wished he could have access to the kind of pieces we have access to,and information from forums like this.
