Pictured is a Human Hair Closure unit by Sensationnel Premium Now Brand. This closure cost about $15.00. Yes! That is expensive when you can now buy a whole package of "inexpensive" weaving hair for the same price. However, you get what you pay for! For those who desire a full head of extensions to allow their hair to rest, this little closure delivers a nice finish for a hairstyle with a bang.
You can sew into the net to anchor the unit to a braid. Trim the net by cutting with regular shears. Add additional hair or wefts to the netting of the unit. At the $15 price point, the quality of hair is going to look nice and hold up. However, these higher quality closure pieces are harder to find because many people do not want to spend $15 for a "center piece" when they still have two packages of "weaving hair" to purchase to get a complete hairstyle.
Below is a tag from a Janet brand Human Hair closure unit. It has H/H Top Pcs on it meaning Human Hair Top Piece. This Janet closure was only around $5.00 but it was short in length with around 8 inch hair on a smaller net.
