I’m new to competing, and will start in September. How should I put up my long hair? (Im a dude).

I use those little soft scrunchy-like hair ties that fold over at the edges and put it in a high ponytail, then wrap it in a bun. It’s great but it comes out sometimes if I’m going super hard and I don’t wanna break a rule or get my scalp torn off or something. I’m putting this both here and in a different sub because I have a feeling there will be plenty of “this doesn’t go here” comments, but I felt like only other Judokas would know the best way for a Judoka to do Judo.
