Following a radical make-over, Sindy relaunched in Selfridges and toy catalogues at the end of last month.
The brand will be promoted in its first ad campaign for several years later this month. The ads will feature the first computer-generated images of the doll.
The advertising, created by specialist agency Optical Image, will run in children's TV slots on digital and terrestrial channels.
100% Design & Development, a joint venture between licensors Pedigree and New Moons, oversaw the relaunch.
Last week Barbie owner Mattel revealed that global sales had slumped by 13%.
