Featuring a lace insert that creates the look of natural scalp along the part. This great band replaces sticky tape and glue. Holding your Wigs securely for an extra boost of confidence. Your Wigs won't budge!!! Very soft and comfortable! They also feature a strip of silicone on the underneath side of the band for extra security and comfort.  Available in 2 colours.

How to use:
Simply wrap the band around your hairline, or wherever your wig meets the scalp, brush your hand across the 3" width of band both ways. You will find one way feels rough and one way feels smooth. You want the rough direction to face from the front to the back of your head. This provides the secure grip from the band to yoir wig. If you get it the wrong way around the wig will still move. So you will know when you have it on right.
