When I was young, I used to ride a triceratops, and I used scissors on hangnails. Problem I found is it is hard to get flush cut with scissors. Which means that the flag of skin is still out there to snag on stuff and getting dirt underneath it.

Try the nail clippers. I think you will find it is easier to flush-cut the skin flag. Once you do I suspect you will give up the scissors.

In a pinch I can still use scissors or even a very sharp blade and whittle down through the skin flag. I've also whittled finger nails but clippers are faster and easier.
