Can anyone tell me what material is the perimeter of this piece? I've been wearing for about a month and a half but find it very hard to tape on the front of this piece. As you can see I use clips and tape but I am considering bonding to my head cause I hate taking it off everyday. Does anyone know if this material can be bonded for a long period of time? And any tips on getting it to stay bonded? I've tried a few different tapes. So not sure if it's that or the material of the piece. Also I don't shave my head is there a tape that will stick to some hair and lay flat? Thanks for any advice!
