TLDR Hair casts can be treated with physical removal and special shampoos.
Peripilar keratin casts, also known as pseudonits or hair casts, are thin, elongated, greyish-white, cylindrical structures that encircle the hair shaft and can be easily slid along it. These casts can be clinically misdiagnosed as nits. Treatment includes physical removal and the use of keratolytic lotions or shampoos. The document reported a case of an 11-year-old girl with pseudonits, highlighting that while the condition is not rare, it is often underdiagnosed.
