The process of adding hair to a lace unit is called ventilation. And it's a tedious any frustrating job. The hair has to be inserted into the lace and then knotted-a tricky procedure with a strand of hair. Some customers have tried to do it themselves and given up. They have a new appreciation for the whole process. And you're right-Deb's mom no longer does it. This has been a very frustrating time in the hair business. Lace is very scarce due to the labor required. The factory is emphasizing thin skin stock units as the hair is injected into the base so there is no knotting-and therefore no knot bleaching. The hair looks like it's coming right out of your scalp. I've looked at other suppliers that have lace units but the products are really inferior. The thin skin units are up to Toplace standards-very realistic. People are reluctant to try thin skin units but once they do many realize how good they are. They are excellent with great hairlines. So this is where we're at till things return to normal.
Best,
