It’s not so much fun when it’s a family members hair (or mine!), but if it was my mom’s hair or something, I’d get grossed out, toss out the portion attached to the food, and then move on to another serving.
I’m really lucky that my family still ate my food, even when sometimes a hair would end up in a cookie or something.
I always made sure to put my hair in a ponytail, but having my hair up wasn’t always a 100% certainty of hair-free baked goods. Thankfully, hair in food happened rarely.
