I've never carried a comb,even when I had my own hair.
One thing I have noticed is that some wearers get so paranoid about their hair that it has to look perfect all the time, that for me would be a dead giveaway!
I always think that a less groomed look is more natural looking?

Equally folk with naturally growing hair like it perfect or messy

My Mantra

I agree with all of you. Since wearing 30 years ago I always wear them messy from day one. You can spot a hair piece at a 100 feet when they are perfectly groomed, especially when the bangs swoop across the forehead.

I also found using a large tooth comb helps it look more natural too.

One of the reasons I asked about a comb is lately I've tried using some sort of hair cream like brylcream. I'm still out on whether I like it or not but what happens is after being in the wind it tends to let the hair stick up instead of falling back down. So if I'm going to continue trying such products I would need a way to get the hair back under control without running to a restroom.
