Clinical Interest of a Nonchemical Lotion in Head Lice Management

In 2008, a study was conducted to assess the usefulness of trichoscopy, a noninvasive technique for visualizing hair and scalp, in diagnosing hair loss. The study involved 75 female patients with various types of hair loss. The results showed that trichoscopy could identify specific features associated with different types of hair loss, such as alopecia areata and androgenic alopecia, without the need for hair removal. However, the study concluded that further research was needed to establish clear trichoscopy criteria for diagnosing specific diseases associated with hair loss. In another study, an epidemiological approach was used to analyze hair loss in a population of 4506 individuals. The results showed that hair loss affected nearly 20% of the population, with a higher prevalence in men and those over 35 years old. The study also found that hair loss was more often due to emotional stress in women and congenital causes in men. A third study evaluated the efficacy and safety of a nonchemical, suffocation-based lotion for treating head lice. The study involved 108 subjects and found that the lotion achieved a pediculicidal effect (killing of lice) in 91.7% of participants and an ovicidal effect (killing of lice eggs) in 77.3% of participants. The lotion was well-tolerated by almost all subjects, suggesting its potential usefulness in head lice management.
