Parallel to the hairpiece industry there is a religious wig industry. For a few years we have made orders for "sheitel stores" and the bases incorporate an old design which we call a silk sandwich. These orders typically have ribbon and clip edging, but any edge can be used for the general market.

Lately, men have been requesting the same design, because it gives the illusion of single hairs growing out of a scalp. Basically the hair is knotted into monofilament (or sometimes lace) in the traditional way, but on either side of the mono is a layer of China Silk. Silk is not really transparent, so instead of revealing scalp for realism, it creates an illusion of scalp, and the underside is silky smooth. It's also quite cool and breathable and the hair moves naturally.

Unfortunately the front edge is visually not that great, but we recommend an inch of normal lace and bleached knots at the hairline edge.

So it's not new, it's not injected and it's not necessarily lace, but it's a nice old idea that is enjoying a big resurgence these days, whatever you want to call it. Anyone selling "injected lace" or "iLace" probably has this product because you cannot actually inject a hair into lace, which is woven polyester. There needs to be a knot, albeit a hidden one. They may be describing it in a questionable way, but it will most likely be excellent.

Perhaps, because the hairs poke through the top layer of silk, that justifies the name injected, but it's actually knotted inside the sandwich.

There are two basic variants. Original 3 layer, with a nice smooth silk layer on the bottom or 2- layer with the lace and knots on the bottom and no third silk comfort layer. Each has silk as a top layer with the hairs individually poking through.
