Yeah, I have traction alopecia on the sides & back of my scalp. The guy/salon I used to go too used to fit my hair using velcro!! Used Gaffa tape with super glue to attach one velcro side on the sides & rear of my hair, then glue the other velcro piece on my pieces poly perimeter so it lined up. This has caused an obvious lack of hair. All this so I could remove each night, ffs, when I think back. He kept me in the dark about pretty much everything to do with hairpiece attachments etc, while charging loads of dosh for what I now know was a shite service. Thank God for the internet for providing hair wearing enlightenment, Amen.
