Disease description:
Since last year, I've been experiencing constant hair loss, and now I have very little hair left on my head. What underlying medical conditions might thinning hair indicate?

Sparse hair may indicate anemia, as anemia reduces red blood cells and decreases oxygen supply to the scalp, leading to hair loss. Sparse hair can also signal infectious conditions of the scalp, such as folliculitis. Since there are many possible causes of hair thinning, it is advisable to visit a hospital for proper examination, identify the underlying cause, and receive targeted treatment accordingly.
