Just be careful- dampen her first, some put snake in very damp towel & pillowcase to let them do it themselves. Personally I usually mist & manually help, but you
don't want to damage her skin by pulling off anything that doesn't come off easily. Sometimes a shallow soak is needed (for shed that's really stuck-on) but that can
be overly stressful for a new snake. When you are gentle with snakes, they mostly seem to realize you're helping...it's no fun for them to get stuck in their old shed.
You're on the way to being a very good snake-owner...(While some might just raise the humidity of her cage & wait for the snake to shed by herself, the extra
time usually just means it gets dryer & even more stuck on, especially since it sounds like the humidity was too low before.)
