The episode on head lice dives into the specifics of what these tiny parasites are and why they’re so common, especially among school-aged children. Carol Johnson, a trichologist, sheds light on the biology of head lice, explaining that they are small insects that live on human hair and feed on blood from the scalp. They are highly contagious, primarily spreading through direct head-to-head contact.

Johnson also addresses the common myths about head lice, like the belief that they are a sign of poor hygiene, which is false. In fact, lice can affect anyone, regardless of hair cleanliness. She talks about the importance of early detection and the telltale symptoms, such as itching, and how to check for lice or nits (lice eggs) at the base of the hair.

Treatment options are explored, including over-the-counter treatments and home remedies. Johnson emphasises that while treatments are effective, it’s crucial to follow instructions precisely to ensure complete eradication.

Additionally, she discusses preventative measures, such as keeping long hair tied back and avoiding the sharing of personal items like hats and combs. Parents are also encouraged to regularly inspect their children’s hair, especially after school vacations or when returning from camps or sleepovers.
