Do you need a hook to take off a rainbow loom braclet?

No you do not.

No, you do not need a hook to take off a Rainbow Loom bracelet from the loom. Bracelets of most designs can be removed easily by lifting and gently stretching the bracelet from the end of the loom where you completed the looming, that is, lifting from the ROUNDED side of the pegs. Lifting the bracelet from the OPEN side of the pegs has a greater risk of catching a band on the edge of a peg and breaking the band.

> .... However, a hook can be helpful when lifting bands from any peg that has a great number of bands wrapped around it, such as a peg with a cap band, and pegs holding the neck and shoulders of action figures.
