When a person comes into contact with these items, infestation may occur. Any human is a potential host. Good personal hygiene does not necessarily prevent lice infestation. Inspect scalp at crown of head, behind the ears and nape of neck. They adhere firmly to the hair shaft, usually near the scalp.
Live lice are the size of a small ant, but well camouflaged and move quickly from light.
Use only as directed. Be aware that the shampoo is chemical and excessive use can cause skin and eye irritation. The residue remains in the hair for several weeks. Overuse can also lead to resistance of lice to these chemicals. Nit combs included with treatment packages are effective tools.
