HP, my show helmet is an XL, schooling a L, too.

Okay so Yuku just ate my post

My sister has really really thick hair, and until August it was really long (then she chopped it alllllllll of D:). Here's what we did (it takes about three people):

- Put your hair in a low ponytail
- make sure its covering your ears how you want it
- split the ponytail into two seconds
- twist the first section
- wrap it around your head going past your ear and around the front of your head (kinda like heidi braids, i guess?)
- bobby pin that sucker down!!
- repeat that with the second section
- put your hairnet on REALLY carefully
- put your helmet on starting from the BACK of your head, you might have to put your head upside down to make sure you get all the ends in the helmet

My sister doesn't take her helmet off all day, and sometimes the bobby pins get poky, so she just takes a couple advil. Good luck!
