The hair up tool is a special device that allows you to do many different styles of updos. It can also be used for pigtails and buns. The hair up tool can be very helpful for those with one hand or reduced function on their hands. It is a long elastic with a toggle on it and can be used in a variety of ways to create ponytails, pigtails and buns. It can be used by people with one hand or with reduced hand function and is simple to use.
Scrunchis are also back in fashion and they are much softer on the hair than regular hair elastics. You can find a variety of them on Etsy. You can also find a bun cage which is similar to the scrunchi but it is made of a hard material like metal or plastic and holds on to the bun with a stick.
