Long hair suddenly becomes "shorter", with blunt and rounded ends. Perfect for when you're out and about and don't want your long hair getting in the way. Imagine being with someone the whole day like this, and then getting to "untie" the hair once you get home and then playing with the full length.

I wish there were more vids like this out there - I'm sure there must be.
