Can You Get Lice From Not Washing Your Hair?

No, you cannot get lice from not washing your hair. Lice are only contracted when you get them physically or through an object like a hat or bedding used by an infected person.

When you wash your hair, it strips off its natural oil secretions, preventing the lice from effectively attaching to strands, moving, or feeding. Therefore, washing your hair makes it easier for lice to maneuver through it, attach eggs to hair strands, and breed.

In contrast, if your lice infection is mild and no eggs have been laid, washing your hair often can eliminate it. However, this is not an effective method of lice control.

Contrary to popular belief, lice infestations are not caused by poor personal or home hygiene, long hair, or being outdoors. Instead, the following elements can cause lice infestations on your mattresses;
