Full face are hot unless it is winter but then again I live in 100F+ weather. Chances are if she isn't afraid to get back on the bike she might not even want to ride it with a full face once she tries it out. She should just stick to the regular helmet. If she knows any better she will be cautious and not do whatever she did again. I'd only look into a full face if there was a broken face or stitches personally.
