Hair band

Clara Oswald had a hair band that she used to keep the A113 running when trying to defeat the Boneless. Instead, the Boneless destroyed the train, so the plan was unsuccessful. (TV: Flatline)

Other companions of the Doctor such as Martha Jones, (TV: Smith and Jones) Bill Potts, (TV: The Pilot) and Yasmin Khan (TV: The Woman Who Fell to Earth) used hair bands to tie their hair up.

Jackie Tyler often wore a band that tied her hair in a ponytail. (TV: Rose et al.)
