the no knot hairnets are really amazing!! they make your hair fit no matter the length.
if you can't find these, i used to use two one knot hairnets, so that the hair would stay in.
I have long and thick hair and I have a hair net that makes my hair into a sock not literally but still it's at green hawk and it's not a lot of money it's worth it
I French braid my hair and put it in a bun and then in my hair net. Then you can apply your hat or helmet 🙂
For me I have a hair tube! It works so much better for me! :)
