The tape is made by Walker. I'm getting a solid week out of it currently. I work out 4 times a week and have my head under the hot shower everyday. Previously, the best hold I could get was with NX Gen glue but for me, the tape is much better. I've not had any lifting at the hairline since using it and my forehead gets pretty oily.

I don't think John sells it in the store. I buy from HD. Here's a link to it.
