I’ve had my teeth whitened 6 months ago which turned them completely white, however they begun turning yellow and I’m wondering what causes this and how can I avoid it

Teeth are actually naturally an off-white color. Even the cleanest of teeth, with zero plaque or damage (cavities, gingivitis, etc) are a bit of a dull cream-yellow. That’s the pulp and inner tissue of your tooth, just a bit visible through the enamel! Pretty neat, right?
I’m not entirely sure how teeth whitening is done these days, but I assume it bleaches the surfaces or coats them in a white surface to cover the visible pulp. Overdoing it can damage and hurt your teeth, because that soft eggshell color is meant to be there.
