I've not tried a clip on wig / hair system, but I think they wouldn't be as securely attached as those using tape or glue. I think they're quicker and easily to attach and remove, though. Don't clip on hair systems go over your bio hair as opposed to a balding area too? I'm not entirely sure. I wear a longer hair system (8 to 10 inches on average) and I've always just shaved the balding bio hair on top and attached to hair system with tape and glue, which integrating it with the bio hair on my back and sides. I think this seems more real than a clip on system. Also, if you want to try different styles and lengths of system without the hassle, a clip on might be a good starting point. Maybe they are more detectable though, especially by touch, and less secure so more risky. You need to research some articles and videos about them really then give them a try.
