Need an Alternative for pulling my Hair together at Work.

Sup everyone.

I work at a Meat section from a Supermarket so now that Mt Hair is so "long" I can't Kerl it under my Cap I am required to.pull it in a Bun or Tail.

No big deal on its own,I plan to do that anyway when it's long enough.

However since I'm not there yet I have to pull it really tight ao much that it hurts and pulling and possibly damaging my roots.

Anyone got a more "gentle" alternative?
