fungal infection causing white nodules on hair shafts
White Piedra is a fungal infection of the hair shaft caused by the yeast-like fungi of the genus Trichosporon. It is characterized by the presence of soft, white to light brown nodules that encase the hair strands, typically affecting the scalp, beard, mustache, and pubic hair. This condition is generally benign but can be treated with antifungal medications and improved hygiene practices.
