The best remedy for removing a hair caught in the throat is to dislodge it by eating a banana or piece of bread. The hair will harmlessly move together with the food into the stomach. While passing through the throat, the food will latch onto the stuck hair, which will move into the stomach and be digested and excreted.
The bolus, or small round mass of chewed food, will help dislodge a hair stuck in the throat. There are other issues that may be causing a sensation of hair stuck in the throat, such as acid reflux, smoking, eating spicy food or irritation caused by clearing the throat.
