A number of factors can contribute to your stool smelling like burnt hair, including sensitivity to new food, food allergies, infections, and even moderate dehydration.

Let’s discuss each of these in more detail.

If you have recently incorporated new food into your diet, your body may be reacting to this change, causing your stool to smell like burnt hair. For example, introducing high amounts of protein or certain types of fat into your diet can affect the smell of your stool.

Food allergies can lead to a variety of symptoms, one of which may be changes in the smell of your stool. For example, if you’re allergic or sensitive to certain types of food like dairy or gluten, it could cause your stool to take on an unusual scent.

Infections, particularly those in the gut, can also cause changes in stool odor. Bacterial or viral infections can alter the normal gut flora, resulting in a burnt hair smell.

When you’re dehydrated, your body absorbs more water from the colon, making your stool harder and potentially altering its smell. If your stool smells like burnt hair, consider whether you’ve been drinking enough fluids.

In the case of babies, their poop can sometimes smell like burnt hair due to similar reasons like diet changes, allergies, and dehydration.

It’s also possible that the smell could be due to the baby formula if you’re not breastfeeding.


In conclusion, if your poop smells like burnt hair, it’s essential to take note of any other symptoms you may be experiencing, such as pain, cramping, changes in stool color, or frequency.

These additional symptoms can help your doctor diagnose and treat any underlying conditions that may be causing this change in odor.

However, in most cases, slight changes in stool smell are quite normal and usually resolve on their own. If you’re concerned about persistent changes in the smell of your stool, consult with a healthcare professional.
