Can you digest your own hair?

No, you cannot digest your own hair. Hair is made of keratin, a type of protein that is resistant to digestion. The enzymes in your stomach and intestines are not strong enough to break down keratin. This is why hair remains intact even after it has been swallowed.

In some cases, hair can cause problems in the digestive tract. If a large amount of hair is swallowed, it can form a ball of hair called a trichobezoar. Trichobezoars can cause abdominal pain, nausea, and vomiting. They can also lead to more serious problems, such as intestinal obstruction and malnutrition.

If you are experiencing any of the symptoms of a trichobezoar, it is important to see a doctor. Treatment may involve removing the trichobezoar with a procedure called endoscopy.
