Medical Intelligence & Overview
White piedra is a superficial fungal infection characterized by the growth of white or light-colored nodules on the hair shaft, often affecting the scalp, beard, mustache, and pubic hair. This condition is caused by certain types of fungi, primarily species of the genus Trichosporon. Despite its unsightly appearance, white piedra is usually a benign condition that can be managed with proper hygiene and medical treatment when necessary. It is distinct from other types of hair infections, such as black piedra, due to the color and texture of the nodules formed on the hair strands.
