Type of infection of the hair

**Exothrix** refers to [Dermatophyte](/source/Dermatophyte) infections of the hair that infect the hair surface. This is in contrast to [Endothrix](/source/Endothrix), where a Dermatophyte mainly invades the hair shaft. Using an ultraviolet [Wood's lamp](/source/Wood's_lamp), endothrix infections will not [fluoresce](/source/Fluoresce) whereas exothrix infections will.
