Nit Confusion: Misidentified hair debris commonly mistaken for head lice or nits. Including but not limited to dandruff, fuzz balls, dirt, beach/playground sand, dead nits and more. Typically occurs when a confused person continually believes to find nits in the hair but is unable to identify a live bug.
A Nit (Egg) is tear drop shaped and is attached to the side of the hair shaft ranging in color from off-white, golden brown to brown and is about the size of a strawberry seed. Nits are always the same shape; they are never irregular, fuzzy or smoosh-able. They are glued to the hair shaft and stuck on the side. It feels hard between the pads of the fingers and you will need to use your fingernails to move it down the hair shaft.
DEC plugs (desquamated epithelial cells) may occur when oil glands in the scalp work to compensate for the drying effects of chemical treatments. They are bright, white, irregularly shaped clumps of fat cells stuck to the hair. *
Hair casts are thin, elongated, cylinder-shaped segments of dandruff which encircle the hair shaft and are easily removed by sliding them down the hair shaft with little effort.*
