After a long period of accumulation, the brown tears in the hair will appear very thick.

5: Nasolacrimal duct obstruction

Due to infection, the nasolacrimal duct becomes inflamed and swollen, causing the entire duct to be completely blocked or incompletely blocked, so tears cannot flow through the nose normally. When the tear ducts are drained, they will naturally overflow, thus forming unsightly tear stains.
