Has anyone tried a velour or velvet wig grip band? I saw one today on the Jon Renau website that could be used with a topper instead of using clips or glue in the front of the topper where hair is thinnest. My topper has a double silk section at the crown (Fortune) which I'm very happy with but the clips at my temple areas are causing traction bald patches. What sort of velvet do they use that would grip the inside of a silk cap topper?
