Plain English Summary

Background and study aims:
Head lice are tiny insects that live in hair. They are a common problem, particularly among school-age children. Head lice are spread by direct head to head contact. Although they are harmless, the bites of these lice can cause itching and can be very frustrating for sufferers. Fulltec Anti-Lice Protector is a shampoo based on vegetable oils that is claimed to kill lice by blocking spiracles, usually applied for 15-30 minutes. The aim of this study is to test the effectiveness of Fulltec Anti-Lice Protector in the treatment of head lice using a shortened application time

Who can participate?
People aged 2 years and over who have head lice.

What does the study involve?
Each consenting participant with confirmed louse infestation is treated by applying the Fulltec Anti-Lice Protector to pre-washed and towel dried hair and left for 15 minutes, rinsed and dried to check that this application time is long enough to be effective. This procedure is repeated after 8 days. The prescence of headlice are then looked for by combing to look for lice on days 1, 8, and 16 after the initial treatment.

What are the possible benefits and risks?
If the treatment regimen is successful participants benefit from getting rid of their head lice completely. There is a small risk that some participants may experience irritation of the scalp from the shampoo or dryness of the skin afterwards.

Where is the study run from?
Medical Entomology Centre, Cambridge (UK)
