Considering this, what is a hair cast?
Hair casts (HCs) are thin, elongated, firm, whitish cylindrical concretions which ensheath the hair shaft and can be easily dislodge. They are of two different types: peripilar and parakeratotic keratin cast. Due to its clinical resemblance to pediculosis capitis, the entity is also known as pseudonits.
what causes Pseudonits? Hair casts, or pseudonits, are another common cause of white bands or nodes along the hair shaft. Hair casts are remnants of the inner root sheath that encircle hair shafts. The casts are thought to result from the failure of the inner root sheath to disintegrate before the hair emerges from the skin surface.
Keeping this in view, are hair casts lice?
Mature head lice are about the size of a sesame seed. Lice eggs are clearly attached to one side of the hair shaft. DEC plugs and hair casts surround the hair shaft. This dandruff like scalp debris also sticks to the hair shaft like a nit but they are white and slide easier.
What color are hair casts?
Peripillous sheaths, also called pseudonits or hair casts, are white-to-yellow tubular structures that encircle the proximal hair shafts of the scalp.
