What are headlice?Headlice eggs in the hairLice are small, flat insects about 2mm to 3mm long that breed all year round. They live on the hair and come down to the scalp to feed and lay eggs. They feed on blood by sticking their tube-like mouthparts into your scalp several times a day. Headlice, nits, cooties - call them what you will - parents tear their hair out trying to treat them. So, how do you deal with headlice, and why do some treatments fail?
