New employee!

Hey I just got hired as a shift leader and I’m super excited about it and I hope I am good at it when I know everything but I have a question!! How are we supposed to wear our hair? I have long hair so I just put it in a bun but could I wear a braid while in a ponytail? And am I allowed to have like 2 strands of my hair (super short) to frame my face? I just don’t like how my face is out in the open u know? Is this too niche?
