I am not sure if there's a word for it, but if there's no word for it what's the next best way to say it, is there a short phrase or something you can think of?

Hair that is still on someone's head, and bound together for neatness or style would usually be called a "ponytail". https://en.wikipedia.org/wiki/Ponytail
Hair that has been cut off and bound together in order to be kept as a form of keepsake would be called a "lock of hair". https://en.wikipedia.org/wiki/Lock_of_hair

Hair has strands. As in:
She had a strand of hair hanging down in her face as she washed the car.
- (Loose) strands of hair can be held in place with bobby or hair pins.
- Strands of hair can be held in place with barrettes or clips.
If two dogs or cats fight, they might rip out hunks of each other's hair.
The hair on your shower floor could be called a blob of hair (though that sort of turns the stomach).
