TLDR The girl's "dandruff" was actually harmless hair casts, not a hygiene issue.
The document presented a clinical case of a 12-year-old girl who experienced persistent "dandruff" despite using various shampoos and lotions, which caused significant anxiety due to misconceptions about hygiene or lice. The condition was identified as peripilar sheaths, also known as hair casts, which are white-yellowish tubular structures that encase hair shafts on the scalp. These sheaths are composed of keratinized cells from the hair's root sheaths and can slide along the hair without breaking it. The authors reported no conflicts of interest.
