Discovering a hair in your otherwise delicious meal can be quite unsettling. Whether it’s a long strand suspiciously resembling spaghetti in your cacio e pepe or something decidedly not yours, it’s a common experience that leaves many wondering: Is Hair In Food Dangerous? Let’s untangle the facts.

What Exactly Is Hair?
Hair, though originating from follicles on our scalps, is not a living entity. According to Dr. Amy K. Bieber, a dermatologist at NYU Langone, hair is primarily composed of keratin. Keratin is a tough, insoluble protein that also constitutes our skin and nails.
The Big Question: Is Eating Hair Dangerous to Your Health?
Generally, swallowing a strand or two of hair is unlikely to cause any immediate harm. Our digestive system lacks the enzymes to break down keratin. Dr. Bieber explains that “the hair itself just goes through your digestive system and comes out in your poop.” It’s a rather unappetizing thought, but not inherently dangerous in small quantities.

Interestingly, we unknowingly consume hair-derived substances regularly. L-cysteine, an amino acid found in keratin, is often used as a dough conditioner and preservative in food processing to enhance the elasticity of bread and baked goods. While the source of L-cysteine is often purified poultry feathers or animal hair, the quantities are small and regulated.
However, consuming large amounts of hair can potentially lead to gastrointestinal discomfort. In rare cases, it may even result in a trichobezoar, a hairball lodged in the stomach or intestines, potentially causing blockages and digestive issues. Trichobezoars are more commonly associated with trichophagia, a compulsive hair-eating disorder.
Germs and Hair: A Cause for Concern?
While individual hairs themselves don’t harbor a significant amount of harmful pathogens, there’s a possibility of bacteria, fungi, yeast, or other microbes clinging to the hair shaft from the environment or our scalps. Staphylococcus aureus, for instance, can affect hair follicles. However, Dr. Bieber assures us that the likelihood of a few hairs harboring enough dangerous microorganisms to cause significant health issues is low.
Specific hair infections, such as white piedra, can grow on the hair shaft. However, these are uncommon. Even if ingested, they are unlikely to cause harm. It’s worth noting that any organisms present on someone else’s hair are likely organisms you’ve already encountered through your own hair, skin, and nails.
The Bottom Line: Should You Worry About Hair in Food?
Finding hair in your food is undoubtedly unpleasant. While the risk of serious health issues from a stray strand is minimal, consuming large quantities of hair should be avoided. Maintain good hygiene practices when preparing food to minimize contamination.
