Hi Jim in my short experience I have never woken up and found the hair elsewhere (Im a restless sleeper too) prob a bit of lift in the lace that you need to contend with in the morning thats about it. The only time I have come close to losing the small systems I use was when I used basebond for a couple of days had a hot bath went compleatly under the water and when I came out I came out without one of the pieces (ps I use 2 small pieces at the hairline)
