I think I should definitely let the glue dry for longer. It's weird cuz in most other uses of glue, you attach whatever you need as soon as possible, usually while the glue is still wet. I'm pretty conscious of cleaning my base and scalp as thoroughly as I can. At first I thought the moisturizing and silicone agents in my shampoo were effecting the lace and my scalp from reaching the glue. But from what I keep reading now their might be something to letting that glue dry a bit longer.
