The question "Why does my hair smell bad?" is an inquiry into the unpleasant odor emitted by the hair. This unpleasant odor can manifest as a musty, oily, or sour smell, which can be both embarrassing and a source of discomfort.
Understanding the causes of hair odor is crucial for maintaining good hair hygiene and preventing the recurrence of this issue. The diagnosis of the underlying cause can also have implications for overall health, as certain medical conditions and dietary deficiencies can contribute to hair odor.
