This page will be a mixture of general information on lice and their control, discussion of oils commonly purported to be useful against lice, and oils that I tested on lice in the laboratory which work very effectively. Based on these results, I shall list other possible oils that can be used and a protocol for lice treatment. But first some general facts. The life cycle of the louse is about 4 weeks. Approximately 8 days are spent in the egg stage, which is the hardest stage to kill.
Female lice are larger than males.
Lice eggs are opaque. If they are clear, it means the lice have already hatched out. Healthy lice and eggs are found only within 1 cm of the scalp. Head lice are not a sign of bad hygiene. They prefer clean hair to dirty hair.
