What are DEC plugs?
Skin can become irritated after using a pediculicide. This can result in the formation of desquamated epithelial cell plugs (DEC) which people often mistake for nits. This causes many caregivers to overtreat with chemicals thus continuing the cycle. If you are not sure if you are seeing nits, take a suspected nit on a hair shaft to your doctor and have him confirm the diagnosis by looking at the suspected nit under a microscope.
