I agree with John. I think the most important thing is to match the density with your sides and back. That's what always gives it away (provided you don't have one of those really bad toupees): the thick, healthy looking hair on top and super fine hair on the sides and back. I think it's super important to show a little scalp. At least in my opinion.

Those pics look great, incredibly natural. You look like someone with fine hair, fine meaning thin. But a hairpiece? Ha, not in a million years.

This hairpiece, if shown to joe public, would crush people's myths about "rugs". nice job man
