Actually, My hair is pretty thick and I tape over my existing hair. I wear my hair fairly long basically a med lenght cut with by todays standards is long..lol I had a templet made that was a little longer than my balding pattern. The hp stays on long and tight to the hair/head. The tape doesnt last quite as long on the hair as it does on my front scalp/skin but since i sleep in it it ends up with a pretty long strong hold from the pressure of sleeping on it. I would get a week+ hold with walker (which would easily las another week but I like to take the hp off at 6 or 7 days to clean and give my scalp a break/cleaning
