Is the certo pectin used on the hair?

Certo pectin is not typically used on hair; it is primarily a food product used for making jams and jellies. However, some people have experimented with it for DIY hair gels due to its thickening properties. It's important to note that using food products on hair can lead to unexpected results, and there are many commercially available hair products specifically formulated for hair care. Always do a patch test first if you decide to experiment.
