So I finally took the plunge, got my piece, and got it cut in professionally on top of my thin existing hair. I'm attaching behind my hairline where there are some pretty good transplants. After being satisfied with the cut in, I decided to go ahead and shave what was left of my hair underneath where the piece will go. Problem is, there is still enough hair that the tape (ST-30) seems to be only attaching to my hair and not to my scalp. I took a shower with it on, just to see what would happen when it got wet. It came off almost instantly with very little difficulty. Does anyone have any advice for me? And could people please comment generally on their experiences with wearing in the water (shower, pool, ocean, etc.) Thanks!!
