can i dye my hair with product in it

Hey! You know, it's best to avoid dyeing your hair with product in it. The presence of styling products may obstruct the coloring process, and you might not achieve the expected results. Always ensure your hair is completely clean before coloring.

Most likely that's the case. Hair dye's job is to penetrate the hair shaft and change its color, but if there's a layer of gel, hairspray or other products on your hair, it can prevent the dye from doing its job properly.

Best is to thoroughly wash your hair, just like you'd normally do. You can then let it air-dry before applying the dye. If you're still uncertain, then it's always smart to ask a professional.
