As we dive into complex methods of application of hair weaves and wigs, I think it is important that we touch on some of the basic jargon for those of you who may not be familiar with the language. The first of this series is the difference between a closure and a frontal. For more information in a quick but informative comparison and contrast, keep reading.
A closure acts as the name suggest. Closures close the top portion of the wig or sew-in so that it is complete. Hair wefts, more commonly referred to as "tracks", are sewn or glued around the cap and an opening is left at the top. This opening is closed by a lace or silk-based closure.
Closures come in various sizes and shapes. In my experience, I've come across a 2x6, 4x4, 4x5, 5x5, 6x6 and lately 7x7.
